SG3524 Buck-Boost Type DC-DC Converter SOIC-16 SMD IC

The SG3524 is a versatile, monolithic integrated circuit that provides all the essential functions for building a regulating power supply, inverter, or switching regulator. Housed in a compact 16-pin SOIC package, this IC is ideal for a wide range of power control applications. It is specifically designed for switching regulators of any polarity, transformer-coupled DC-to-DC converters, and transformerless voltage doublers. The SG3524 simplifies power supply design by integrating key components onto a single chip, including a voltage reference, error amplifier, oscillator, pulse-width modulator, and dual alternating output transistors.

• Complete PWM Control: Integrates all the necessary circuitry for Pulse-Width Modulation (PWM) power control.
• Versatile Output Stage: Uncommitted outputs allow for either single-ended or push-pull configurations.
• Wide Operating Voltage: Operates over a supply voltage range of 8V to 40V.
• On-Chip Reference: Provides a stable 5V reference voltage with a maximum temperature variation of 1%.
• Programmable Oscillator: The oscillator frequency can be set using an external resistor (RT) and capacitor (CT), with an operational range up to 300kHz.
• Low Standby Current: Consumes a typically low 8mA of standby current.
• Integrated Protection: Includes current-limiting and shutdown circuitry to protect the power supply and the load.
