Switching Regulator IC with Built-in FET (5V)
No.10036EAT09
- Description BD9757MWV is an 8-channel switching regulator with a built-in FET for digital still camera. It has a built-in function to light-control the white LED for backlight according to the light control setting signal from microputer.
- Features
1) Starting from VBAT terminal of 1.5V 2) Power of internal circuit is supplied from voltage boost CH1 3) Mounted with a total of 8ch including voltage boost 2ch, voltage step-down 4ch, inversion 1ch, and white
LED-purpose voltage boost (patible with DC light control) 1ch 4) Built-in 5-channel transistors for synchronous rectification 5) Built-in 2-channel FET transistors for voltage boost 6) Built-in all-channel phase pensation between input and output of error amplifier 7) Channel 1 and 3 are mon, but other channels are independent, so the ON/OFF is possible 8) Operating frequencies of 1.2MHz (CH1 ~...
