PN6012 power chip pin parameters are as follows:
1 Pin (VCC) : The positive pin that powers the chip, with a voltage range of 3.0V to 5.5V.
2-pin (GND) : The negative pin of the chip, which is connected to the system.
3-pin (PWM) : The pulse-width modulation output pin is used to control the on-off and off-off of the external switching tube.
4 pin (SD) : Turn off pin. When this pin is at low power level, the chip will enter the off state.
5-pin (FB) : Feedback pin that detects the output voltage for voltage regulation control.
6-pin (COMP) : The error amplifier output pin is used to compare the feedback voltage to the reference voltage, resulting in an error signal.
7 pin (ISET) : Current limiting pin, used to set the limit of the output current.
8 Pin (NC) : The pin is not connected and does not need to be connected.
The PN6012 is a DC-DC converter power chip with constant current\/constant voltage (CC\/CV) control mode. It has the following pin parameters:
- VIN: Input voltage pin, connected to the power input.
- GND: indicates the ground cable pin that connects the ground cable.
- VCC: connects the power supply voltage to the chip power supply pin.
- EN: Enables pins. The chip is enabled at high level and the chip is disabled at low level.
-FB: Feedback pin used to detect and adjust the output voltage.
- CS: Current detection pin, used to detect and adjust the output current.
-SW: Switch pin, connecting inductors and diodes, used to switch current.
- BOOT: indicates the bootstrap capacitor pin, which connects to the bootstrap capacitor and provides voltage for the high-voltage switch.
