BD9011KV-E2

Dual-output, high voltage, high-efficiency step-down Switching Regulator (Controller type)

ROHM Semiconductor 

●Description

BD9775FV,BD9011EKN/KV is Switching Controller with synchronous rectification(BD9775FV is 1channel synchronous

rectification, BD9011EKN/KV is 2channel synchronous rectification.) and wide input range. It can contribute to ecological

design(lower power consumption) for most of electronic equipments.

■BD9775FV (1channel synchronous rectification configuration)

●Features (BD9775FV)

1) 2channel Step-Down DC/DC FET driver

2) Synchronous rectification for channel 2

3) Able to synchronize to an external clock signal

4) Over Current Protection (OCP) by monitoring VDS of P channel FET

5) Short Circuit Protection (SCP) by delay time and latch method

6) Under Voltage Lock Out (UVLO)

7) Thermal Shut Down (TSD)

8) Package : SSOP-B28

●Applications (BD9775FV)

Car navigation system, Car Audio, Display, Flat TV

●Absolute maximum ratings (Ta=25℃)(BD9775FV)
