7 Channel Switching Regulator Controller for Digital Camera that contains an internal FET.Built in the function that dim a white LED for back light with a diming set signal from a microcomputer.
Feature
- 1.5V minimum input operating
- Supplies power for the internal circuit by step-up converter(CH1).
- CH1step-up converter, CH2cross converter, CH3,4 step-down converter, CH5 inverting converter for CCD, CH6 boost converter for CCD, CH7 boost converter for LED
- All channels contain internal Power MOSFET and compensation.Built-In Over Voltage Protection (OVP) for CH1,2,7
- Operating frequency 2.0MHz(CH3,4)､1MHz（CH1,2,5～7）
- Contains sequence control circuit for CH1～4. It is possible to select sequence CH1⇒CH3⇒CH4⇒CH2 and CH1⇒CH4⇒CH3⇒CH2 by SEQ_CTL pin
- Built-In discharge switch (CH2,3,4) and contains off sequence control circuit for CH1～4. CH1,3 turn off after CH2,4 output voltage discharged.
- Built-In Short-circuit Protection (SCP)
- CH1 have backgate control circuit CH6 have high side switches with soft start function.
- Thermally enhanced UQFN036V5050 package（5mm×5mm, 0.4mm pitch）
