Function
The serial data input pin which used to receives 8-bit wide serial data.
The shift clock input pin which takes the input signal of DI pin to 8-bit shift register by the
rising edge of the clock signal.
When CS pin is "Low", this pin can receive the data into the 8-bit shift register. The each
bit will be latched at rising edge of the clock signal.
The output pin of the amplified A/D input.
The reference voltage output pin of the A/D converter.
The A/D converter input pin.
The current sense input pin.
The input pin for the current detection to feedback of sub-switch driver.
The sub-switch driver output pin.
The main switch driver output pin. (Open collector)
The LED driver output pin. (Open collector)
The stabilized +5 V output pin.
The pre-drive pin which used to connect the external PNP Tr.
The power supply pin.
The current detection input pin.
The input pin for current detection adjustment.
The voltage detection input pin.
The feedback pin for voltage and current control.
The inverted input pin of OP-amp.
The non-inverted input pin of OP-amp.
The OP-amp. output pin. (Open collector output)
The ground pin.
The ground pin of power unit. (Main switch driver and LED driver)
The output pin of Reset and WDT. (Pulled up to VDD)
The pin used to connect capacitor to determine the time constant of WDT.
The input pin of the WDT.
The pin used to connect capacitor to determine delay time the output after the Reset.
