IEEE 802.3bt PD Controller

Linear Technology Corp. recently introduced the LT4295IEEE 802.3bt powered device (PD) interface controller for applications that require up to 71 W. The next Power over Ethernet (PoE) standard—IEEE 802.3bt—enables manufacturers to go beyond the 25.5 W allocated by the 2009 IEEE 802.3at standard. The new standard—PoE++ or 4PPoE—increases the power budget to enable new applications and features, while supporting 10GBASE-T and maintaining backward compatibility with older IEEE equipment. The LT4295 is IEEE 802.3bt (Draft 2.0) compliant and supports newly introduced features, including all additional PD classes (5, 6, 7, and 8), additional PD types (Type 3 and Type 4), and five-event classification.Linear-LT4295

Its dual channel design delivers independent 2.5- and 1.5-A continuous current to outputs as low as 0.8 V. A dual channel synchronous rectification topology delivers up to 95% efficiency while Burst Mode operation keeps quiescent current under 6.5 µA (both channels enabled) in no-load standby conditions, making it ideal for always-on systems. Switching frequency can be programmed from 200 kHz to 3 MHz and is synchronizable throughout this range.LT8616 Linear

The LT8616’s 35-ns minimum on-time enables 16 VIN to 1.8 VOUT step-down conversions, while switching at 2 MHz helps you avoid critical noise-sensitive frequency bands, such as AM radio while having a very compact solution footprint. Its 3.4- to 42-V input voltage range makes it ideal for automotive applications which must regulate through cold-crank and stop-start scenarios with minimum input voltages as low as 3.4 V and load dump transients in excess of 40 V. Each channel of the LT8616 maintains a minimum dropout voltage of only 400 mV (at 1 A) under all conditions, enabling it to excel in scenarios such as automotive cold-crank. The LT8616’s 28-lead thermally enhanced TSSOP package and high switching frequency keeps external inductors and capacitors small, providing a compact, thermally efficient footprint.

The LT8616 utilizes dual internal top and bottom high efficiency power switches with the necessary boost diodes, oscillator, control and logic circuitry integrated into a single die. Each channel switches 180° out-of-phase to reduce output ripple. Each channel has a separate input for added design flexibility. Low ripple Burst Mode operation maintains high efficiency at low output currents while keeping output ripple below 15 mVPP. Unique design techniques and a new high speed process enable high efficiency over a wide input voltage range, and the LT8616’s current-mode topology provides fast transient response and excellent loop stability.

Compact 20A Hot Swap Controller Integrates MOSFET & Current Sensing

Linear Technology Corp. recently announced the LTC4234, a 20A Hot Swap controller with integrated MOSFET and current sensing, which provides a small footprint hot-plug solution for high-density circuit boards. The LTC4234 ensures safe board insertion and removal from live 2.9-to-15-V backplanes by controlling an internal N-channel power MOSFET to gently power up bulk capacitors and avoid sparks, connector damage and system glitches. By integrating the two most critical and largest Hot Swap components-power MOSFET and sense resistor, the LTC4234 reduces design time and saves board area. The internal, production-tested MOSFET’s safe operating area (SOA) is specified to ensure a rugged hot-plug solution, especially for space-constrained boards and cards in servers, network routers and switches, solid-state drives, and industrial systems.Linear LTC4234

Upon insertion, the LTC4234 waits for connector contact bounce to finish before soft-starting the output. A ground-referenced signal proportional to the load current is provided for monitoring with an external analog-to-digital converter (ADC). The current limit can be reduced from its 22.5A default with a single resistor, affording quick adjustment for dynamic load changes and various applications. For higher current applications, two LTC4234s are easily paralleled for a 40A solution. During overcurrent conditions, the controller limits MOSFET power dissipation by folding back its current limit for an adjustable timeout period. Undervoltage and overvoltage thresholds protect downstream loads against voltages outside a valid window, preventing circuit malfunction and damage.
