BD9G401EFJ-EVK-001 has been developed for ROHM's non-synchronous buck DC/DC converter customers evaluating BD9G401EFJ-M. While the BD9G401EFJ-M accepts a power supply input range of 4.5V to 42V, and generates output voltages from 1V to VCC, this EVK is setup for the input voltage range of 10V to 42V and a fixed output of 5V can be produced. The IC has internal 140mohm N channel MOSFET and the operating frequency is fixed 300KHz. A fixed soft start circuit prevents inrush current during start-up along with UVLO and TSD, OCP protection circuits. The under voltage lockout and hysteresis can be set by external resistor using EN pin. EN pin allows for simple ON/OFF control of the IC to reduce standby current consumption. In addition, it has a synchronization function with an external clock that provides noise management.
- 3.5A output current
- 93% efficiency
