UC3842BN Description

Short technical summary and product information.

The UC3842BN is a current-mode PWM controller IC from STMicroelectronics, designed for DC-DC switching controller applications. This device is commonly used as the control stage in switching power supplies.

 

The IC operates over a supply voltage range of 10V to 30V, allowing flexible use in various power systems. Its operating temperature range is specified from 0°C to 70°C, suitable for commercial-grade environments.

 

As a current-mode controller, the UC3842BN provides stable PWM control signals for DC-DC converters. It is often implemented in offline power supplies, battery chargers, and isolated converters. The controller's ability to operate from a 10V to 30V input simplifies biasing from the input rail.

 

The UC3842BN is housed in an 8-pin Mini-DIP package, which supports through-hole PCB mounting. The device is compatible with standard DIP sockets and breadboards, facilitating prototyping and production assembly.
