General Description

ROHM’s high efficiency switching regulator, BD9B331GWZ, is a step-down converter designed to produce a low voltage output of 0.6V~3.3V from a 2.7V~5.5V power supply line.

It offers high efficiency in all load ranges by automatic PFM/PWM adjustment.

It employs an On time control system to provide faster transient response to sudden change in load.

Key Features

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. Key Specifications.
Input Voltage Range: 2.7V to 5.5V.
Output Voltage Range: 0.6V to PVCC×0.8V.
Output Current: 3.0A (Max).
Switching Frequency: 1.
