New FMEA-Compliant µModule Regulator

Linear Technology recently introduced the LTM8003 step-down DC/DC µModule regulator. With a 40-V input voltage rating and 3.5 A of continuous output current, the LTM8003’s pinout is failure mode effects analysis (FMEA) compliant, so the output voltage remains at or below the regulation voltage in the event of a short-circuit to GND, a short-circuit to a nearby pin, or if a pin is left floating.  Linear 8003

The LTM8003 operates in four operation: Burst Mode, pulse skip mode, pulse skip mode with spread spectrum, and external synch mode. The quiescent current in Burst Mode operation is 25 µA (max), which makes the LTM8003 a good option for battery-operated systems.

The LTM8003’s specs and features:

  • Wide Input Voltage Range: 3.4 to 40 V
  • Wide Output Voltage Range: 0.97 to 18 V
  • 3.5 A Continuous Output Current (6 A Peak)
  • FMEA-compliant pinout
  • 150°C maximum operating temperature (H-Grade)
  • Selectable switching frequency: 200 kHz to 3 MHz
  • External synchronization
  • Low quiescent current = 25 µA
  • Programmable soft-start
  • 6.25 mm × 9 mm × 3.32 mm BGA package

The LTM8003 starts at 1,000-piece pricing starts at $11.30 each in 1,000-piece quantities.
