Power LSI series for Digital Camera and Digital Video Camera

4CH Internal Power MOSFET

System Switching Regulator

BD9866GUL

●Outline

BD9866GUL is a 4ch DC/DC converter IC composed of

Buck converter 3-channels and Buck-Boost converter

1-channel.Including power MOSFET of all channels

reduces the number of peripheral devices. Each

channel is controlled individually, that enables to reduce

power consumption of not working channel.

●Features

1) Includes Buck converter (CH1, 2 and 4), and

Buck-Boost converter (CH3), total 4 channels

included.

2) Includes Power MOSFET for all channels.

3) Includes Over Current Protection (OCP) for all

channels.

4) Includes Short Circuit Protection (SCP.)

5) Includes Undervoltage Lock Out (UVLO.)

6) Includes Thermal Shut Down (TSD.)

7) Includes Power Good(PG)

8) External synchronous oscillation

9) Each channel can be turn on/off individually.

10) Contains internal compensation for all channels.

11) Operation frequency of 1MHz.

●Package

WLCSP(3.75mm×3.75mm)

●Use

For digital single-lens reflex camera, digital video

camera.
