Highly Integrated USB-C Buck Charger Reduces Size by 30%

Maxim Integrated Products has announced the MAX77860 3A switch-mode charger. This USB-C buck charger provides the industry’s first integrated USB-C port controller and charger to eliminate the need for a separate host controller, according to Maxim. This simplifies software development and reduce overall bill-of-materials (BOM) costs for applications such as financial point-of-sale terminals, power banks, industrial computers, scanners, radios, medical devices and charging cradles.
To reduce design size as well as simplify the system hardware and software design, the MAX77860 integrates USB-C configuration channel (CC) port detection and a battery charger for 15 W applications. These integrated functions allow battery charging at the fastest rate possible under the USB-C specification and contribute to 30% smaller design size while also simplifying software development. The CC pin detection feature also shortens the design effort by eliminating the need to support end-to-end USB port connection and allowing charging to start automatically.

Key Advantages:

  • Highly Integrated: Eliminates a separate port controller and many discrete components. Reduces the size of an inductor and a capacitor due to a high switching frequency of 2 MHz/ 4 MHz, resulting in a solution size that is 30 percent smaller than the closest competitive device. This high level of integration also reduces overall BOM costs.
  • High Efficiency: High-efficiency buck reduces heat dissipation with more than 93 percent efficiency and up to 3A charging capability.
  • Design Flexibility: Backward compatibility allows designs to work with both USB-C and legacy BC1.2 or proprietary adapters. Integrated analog-to-digital converter (ADC) frees up resources in the microcontroller, while providing accurate voltage and current measurements.

The MAX77860 is available at Maxim’s website for $3.03 (1,000-up). The MAX77860EVKIT# evaluation kit is available for $70.

USB-C Buck-Boost IC Supports NVDC and HPBB Charging

Renesas Electronics has introduced what it claims is the first USB-C buck-boost battery charger to support both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck-Boost (HPBB) charging for notebooks, ultrabooks, tablets and power banks using the reversible USB Type-C connector cable. Through firmware control, the ISL9241 can switch between NVDC and HPBB modes. The device leverages Renesas’ R3 modulation technology for high light-load efficiency and ultra-fast transient response to extend battery run-time. The charger’s reconfigurable internal registers allow the use of a smaller inductor for HPBB mode to achieve higher efficiencies across multiple power levels.
The ISL9241 delivers charging, system bus regulation, and protection features using NFETs for highest efficiency and bill of material (BOM) cost optimization. The charger can operate with only a battery, only an adapter, or both connected. It takes DC input power from conventional adapters, travel adapters, and USB Type-C power delivery (PD) ports, and safely charges battery packs with up to four-cell Li-ion series batteries.

In NVDC mode, the ISL9241 automatically selects the adapter or battery as the source for system power. NVDC operation also supports turbo mode by turning on the BGATE FET to limit adapter current at the adapter’s current limit set point. NVDC is the ISL9241’s initial startup state before the system controller’s firmware changes the configuration to HPBB. In higher power HPBB mode, the ISL9241 supports bypass, bypass plus charging, reverse turbo-boost mode, and reverse turbo-boost mode plus charging.

The ISL9241 provides 5 V to 20 V reverse buck, boost, or buck-boost operation to the adapter port (OTG mode). This allows configurations to support USB-C PD output for fast charging Programmable Power Supply (PPS) ports. Direct charging the battery can also be enabled by bypassing the ISL9241 in PPS mode. The ISL9241’s reconfigurable charging architecture also allows designers to use the charger for multiport configurations while remaining fully compliant with the USB PD3.0 standard. Several digital telemetry, fault monitoring and protection features are provided. In addition, the ISL9241 also features a supplemental power mode that allows the input bias capacitor to store energy and release it during high power demand.

The ISL9241 can be combined with the ISL95338 buck-boost voltage regulator, R9A02G011 USB PD controller or R9J02G012 USB PD controller, and RAJ240045 fuel gauge IC for a complete USB-C PD3.0 and battery charger solution.

Features of ISL9241

  • Buck-boost NVDC and HPBB charger for 2-, 3-, or 4-cell Li-ion batteries
  • Input voltage range of 3.9V to 23.4V (no dead-zone)
  • System/battery output voltage of 3.9V to 18.304V
  • Bypass mode supports system connection to adapter

  • Supports supplemental power (Intel VMIN active protection)
  • Programmable autonomous charging, and end of charge timer to stop battery charging
  • Integrated 8-bit ADC enables system telemetry: temperature (PCB and junction), adapter current/voltage, battery charge/discharge current, and system bus voltage
  • Compliant with Intel PROCHOT# and PSYS for protection against battery voltage drop, adapter over-current, battery over-current and overheat
  • Allows trickle charging of depleted battery
  • SMBus/I2C allows programming of key parameters to deliver a customized solution
  • Battery ship mode keeps IC in ultra-low power state

The ISL9241 USB-C combo buck-boost battery charger is available now in a 4 mm x 4 mm, 32-lead TQFN package and is priced at $3.90 USD in 1k quantities.
