STMicroelectronics 16-Pin SOIC 2-Channel Voltage Mode PWM Controller 300 kHz 40V SG3524P

STMicroelectronics SG3524P is a 16-pin, surface-mount SOIC package PWM controller designed for precision pulse-width modulation applications in power electronics. It operates with a voltage mode control topology and two output channels, allowing efficient and stable switching in switch mode power supplies.

This PWM controller supports a broad supply voltage range with a minimum of 8 volts and maximum up to 40 volts, making it versatile for various power management situations. It is optimized to switch at frequencies up to 300 kHz, enabling high-speed performance in AC-DC and DC-DC power converters.

Operating with a low supply current of 14 mA and providing output currents up to 100 mA, the device is suited for moderate-power electronic circuits. The maximum duty cycle of 45% balances switching efficiency and thermal characteristics.

The SG3524P is housed in a compact 16-pin SOIC package with dimensions 10 mm by 4 mm by 1.65 mm, supporting surface mount technology for modern circuit board assemblies. It reliably functions within an ambient temperature range of 0 to 70 degrees Celsius.

Applications include isolated and non-isolated switch-mode power supplies, using popular topologies such as fly-back, forward, or quasi-resonant controllers, and double-ended configurations like asymmetrical half-bridge designs. The integrated protections enhance robustness and reliability in demanding industrial, commercial, and electronics manufacturing environments.

Maximum switching frequency is 300 kHz ensuring high-speed PWM control. Push-pull topology optimizes power supply design. Wide voltage range from 8V to 40V for flexible power management. Two output channels enable dual PWM output capability.

Low supply current of 14 mA minimises power usage. Compact 16-pin SOIC surface mount package for easy PCB integration. Operating temperature range from 0°C to 70°C suitable for typical industrial conditions. Maximum duty cycle limited to 45% to maintain operational stability.

Applications in SMPS, DC-DC converters, and AC-DC isolated power supplies. Built-in protections provide enhanced device reliability and robustness. Explore more industrial grade power management ICs and PWM Controllers on EnvMart for efficient electronic design solutions.
