FAQs

What is SG1526J?

The SG1526J is a pulse width modulator (PWM) controller integrated circuit designed by Texas Instruments. It is commonly used for controlling the power delivery in switch mode power supplies, voltage regulators, motor control, and other power electronics applications.

How Does SG1526J Work?

The SG1526J works by generating a pulse-width modulated signal based on the input control voltage and feedback signals. It regulates the output pulse width to control the power delivered to the load, providing efficient and stable power management. The device includes features such as soft-start, overcurrent protection, and onboard error amplifiers for enhanced control and protection.

How Many Pins does SG1526J have and What are the Functions of the Pinout Configuration?

The SG1526J is available in a 16-pin dual in-line package (DIP). The pinout configuration includes:

VREF: Reference voltage input.
COMP: Error amplifier output for the voltage loop.
FB: Feedback input from the output voltage to the voltage loop error amplifier.
SD: Soft-start capacitor pin.
RT/CT: Oscillator timing capacitor pin.
CT: Timing capacitor pin for setting oscillator frequency.
LATCH: Output latch disable input.
IGND: Ground for all the internal logic circuits.
OUT1, OUT2: Push-pull gate driver outputs.
VIN: Supply voltage input.
COMP2: Error amplifier output for the current loop.
VC: Compensated reference voltage output.
