ROHM Semiconductor BD9B331GWZ-E2 Buck DC/DC Converter is a single synchronous step-down converter designed to produce a low voltage output of 0.6V to 3.3V from a 2.7V to 5.5V power supply line. BD9B331GWZ-E2 offers high efficiency in all load ranges by automatic PFM/PWM adjustment. This device employs an On time control system to provide faster transient response to sudden change in load.
Feature
- Fast transient response with On time control system.
- High efficiency for all load range with synchronous rectifier (Nch/Nch FET) and adaptive PFM/PWM system.
- Adjustable Soft-start function.
- Thermal and UVLO protection.
- Short-circuit current protection with pulse count
- Shutdown function.
