Q100/FSQ100 PWM Controller
- FSQ100 consists of an integrated Pulse Width Modulator (PWM) and SenseFET, specifically designed for high-performance, off-line, Switch-Mode Power Supplies (SMPS) with minimal external components.
- This device is an integrated high-voltage power switching regulator that combines a VDMOS SenseFET with a voltage mode PWM control block. The integrated PWM controller features include a fixed oscillator, Under-Voltage Lockout (UVLO) protection, Leading Edge Blanking (LEB), an optimized gate turn-on/turn-off driver, Thermal Shutdown (TSD) protection, and temperature-compensated precision-current sources for loop compensation and fault protection circuitry.

NodeMCU ESP-12E Wifi Module
Operating voltage 5V
Flash memory 4Mb
Processor L106 32-bit
Processor speed 80-160MHz
RAM 32K + 80K
ADC 1, 10-bit
GPIO Pins: NodeMCU has 16 GPIO pins which can be used to control other peripheral devices like sensors, LEDs, switches etc. These pins can also be used as PWM pins.
ADC (Analog to Digital Converter) Pin: It has one ADC channel and can be accessed through pin A0.
SPI Pins: There are 4 pins (SCK, MISO, MOSI etc) available for SPI communication.
I2C Pins: It has I2C functionality support but due to internal use of these pins, you have to find which pin is I2C.
UART Pins: It has two UART interfaces. Since, RXD0 and TXD0 is used to upload codes to board, we cannot use them while programming this module. We can use RXD1 and TXD1 anytime.
