SG3524

The SG3524 is a versatile Regulating Pulse Width Modulator IC designed for constructing regulating power supplies, inverters, and switching regulators. It incorporates complete pulse-width modulation (PWM) power-control circuitry on a single chip, making it suitable for high-power-output applications.

Key electrical specifications include a wide supply voltage range from 8V to 40V, an output voltage range of 4.6V to 5.4V, and a typical output current of 50 mA. The device supports various output topologies such as Boost, Buck, Fly-back, Forward, and Push-Pull, with a maximum duty cycle of 45% and a typical switching frequency of 722 kHz. It also features complementary outputs for single-ended or push-pull applications.

The SG3524 is available in 16-pin packages including SOIC, PDIP, and NS, with specific body dimensions provided for each. Its design includes an on-chip regulator, error amplifier, programmable oscillator, and current-limiting circuitry, facilitating its use with a minimum number of external components for applications like DC-to-DC conversion.

This IC is well-suited for applications requiring precise power control, including desktop PCs, microwave ovens, server PSUs, solar micro-inverters, washing machines, and e-bikes.
