Overview
The SG3524P is a voltage mode PWM controller manufactured by STMicroelectronics, designed for regulating power supplies and switching regulators. It integrates complete PWM power control circuitry on a single monolithic chip. Key electrical parameters include a maximum switching frequency of 300 kHz, a maximum duty cycle of 45%, and an operating supply voltage range of 8 V to 40 V. The device features two uncommitted output transistors capable of sourcing or sinking up to 100 mA, with a typical standby current of 8 mA. It operates within a temperature range of 0 °C to +70 °C and is available in a 16-pin SOIC package.
Feature Summary
- Integrates complete PWM power control circuitry including reference, error amplifier, oscillator, and output stages.
- Features dual alternating outputs suitable for single-ended or push-pull applications.
- Includes built-in current-limiting and shut-down circuitry for protection.
Applications
- Regulating power supplies
- Transformer-coupled DC-to-DC converters
- Switching regulators
Procurement Notes
Verify the specific suffix (e.g., P, N, TR) against the datasheet to confirm package type and tape/reel configuration. Ensure the component meets RoHS requirements if applicable. Confirm the manufacturer part number matches the design specification exactly, as variations may exist between original and STMicroelectronics versions.
Selection Notes
Select this component for designs requiring a fixed-frequency pulse-width modulation technique with integrated shutdown capabilities. The dual output configuration supports both single-ended and push-pull topologies. Consider the 300 kHz maximum frequency limit and 45% duty cycle constraint when designing the timing components and transformer specifications.
Part Context
The SG3524 belongs to a family of regulating pulse width modulators originally developed for high-power-output applications. STMicroelectronics produces variants such as the SG3524N and SG3524P, which share core functional specifications but differ in packaging and commercial availability status.
Replacement Considerations
Compatible substitutes include the SG3524N and SG3525A series, which offer similar PWM control functions. Verify pin compatibility and electrical ratings before substitution.
