System Switching Regulator IC

with Built-in FET (10V)

BD8355MWV

No.11036EAT20

●Description

BD8355MWV is a system switching regulator for Li 2 cell composed of 6 step-down synchronous rectification channels and

1 step-up Di rectification channel for LED application. Using a charge-pump system for high side FET driver and including

power MOSFET reduce the number of peripheral devices and realize high efficiency.

●Functions

1) Includes step-down 6 CH (CH1~6), step-up for LED 1CH (7CH) total 7CH included.

2) Includes Power MOSFET for all channels.

3) Includes Charge-pump circuit for high side driver.

4) Operating frequency of 750 kHz.

5) CH1 and 4 are common, 3 and 5 are also common, and others are possible to turn ON/OFF independently.

6) Includes Short Circuit Protection (SCP), Under Voltage Lock Out (UVLO) and Thermal Shut Down (TSD).

7) Includes Short Circuit Protection for CH6 (SCP6).

8) Includes Over Voltage Protection for CH7.

9) Thermally enhanced UQFN056V7070 package (7mm×7mm, 0.4mm pitch)

●Applications

For digital single-lens reflex camera, digital video camera

●Absolute maximum ratings（Ta＝25℃）
