Electromagnetic-compatible 1A, 36V DC/DC uModule buck converter from Linear

Linear has introduced the LTM8031, an electromagnetic-compatible 1A, 36V DC/DC uModule regulator system that includes the inductor, switching DC/DC controller, power switches, and filters. The suggested applications for the LTM8031 are converting and regulating automotive battery voltage, distributed power supply and high voltage industrial and avionics systems.

The key features of the LTM8031 are,

Complete step-down switch mode power supply
Operating input voltage ranges from 3.6V to 36V
0.8V to 10V output voltage
Switching frequency from 200kHz to 2.4MHz with a resistor or synchronized to an external clock.
EN55022 Class B compliant
Current mode control
Programmable soft-start
Complete DC/DC system-in-a-package

To improve efficiency at light loads, the device automatically activates Burst Mode operation, which keeps the output capacitor charged to the proper voltage with single cycle bursts of current followed by sleep periods, minimizing input quiescent current.

Package: Low profile (9mm × 15mm × 2.82mm) surface mount LGA package
Price: Each $9.95 for 1k pieces
Availability: Now
