ROHM Semiconductor Switching Regulator Boost Converters

ROHM Semiconductor Switching Regulator Boost Converters feature integrated FETs and power MOSFETs with 1-channel and 2-channel variants. These boost converters operate across various input voltage ranges from 0.6V to 5.5V. The switching regulator boost converters operate at temperature ranges of -40°C to 85°C, -25°C to 85°C, -35°C to 85°C, and -40°C to 125°C. These boost converters include synchronous and non-synchronous variants.

Features

Built-in Under-Voltage Lockout (UVLO) protection, Over-Current Protection (OCP), and Thermal Shutdown (TSD) circuits for boost converters with integrated FET
