Description

The STC4614 is a monolithic integrated circuit designed for pulse width modulated (PWM) switching power supplies. It is capable of operating at frequencies ranging from 1kHz to 300kHz and can provide output voltages up to 40V. With a wide operating temperature range of -40°C to 85°C, it is suitable for various applications.

Specifications and features

- Uncommitted output transistors capable of 200mA source or sink

- Internal protection from double pulsing of outputs with narrow pulse widths or with supply voltages below specified limits

- Easily synchronized to other circuits

- Dead time control comparator

- Output control selects single-ended or push-pull operation

Application Scenarios

The STC4614 is commonly used in the design and implementation of PWM switching power supplies. It can be utilized in push-pull, bridge, and series configurations. This component is suitable for applications that require precise control of power delivery, such as power converters, motor drives, and LED lighting systems.
