Charge Pump type

for Flash

BD7700GU

No.11041EAT19

●Description

BD7700GU is a maximum of 300mA LED flash (three-channel total) driver IC. Flash mode and torch mode are controllable

by two external control signals. The flash mode timer ability for a maximum of 1s is carried, and management of flash

lighting time is easy and safe.

●Features

1) Current regulation for LED

2) 3ch High side current Driver

3) Flash LED High side Current driver (Max 100mA@1ch)

4) Torch LED High side Current driver (Max 20mA@1ch)

5) Indicate LED High side Current driver (Max 1mA)

6) High efficiency up to 80%

7) 2port control Flash and Torch and Indicate mode

8) Charge pump step-up DC/DC converter (Max 300mA) Three charge pump mode (×1, ×1.5, ×2.0)

9) Automatically transition to each mode

10) Over-voltage protection / In rush current prevention (soft start) / Over current limiter

11) Under Voltage Lockout threshold / Thermal shutdown

12) Small and thin CSP package

●Applications

Flash and torch of camera for mobile phone
