BD9G101G Simple Step-Down Switching Regulator (42Vin, 500mA)

Simple step-down switching regulator with built-in power MOSFET from ROHM

Image of Rohm's BD9G101G ROHM Semiconductor's BD9G101G is a non-synchronous step down switching regulator. An integrated internal high-side 42 V power MOSFET provides up to 500 mA of DC output current in a tiny SOT23-6 (SSOP6) package. In addition to a small package, a fixed 1.5 MHz operating frequency allows the use of small inductors and ceramic capacitors. No external compensation is required and an evaluation kit is also available for testing.

Features
  • Wide input voltage of 6 V to 42 V
  • 1.5% accurate feedback reference voltage (TA = 25˚C)
  • 1.5 MHz fixed operating frequency
  • 0 µA shutdown supply current
  • Internal over-current protection, under-voltage lockout and thermal shutdown
  • Tiny 6-Lead SOT-23 package (SSOP6)
Applications
  • Industrial distributed power
  • Automotive
  • Battery powered equipment
