TL2842BP Description

Short technical summary and product information.

The TL2842BP from Texas Instruments is a high-performance current-mode PWM controller designed for efficient DC-to-DC conversion. It is suitable for applications requiring switching regulators of any polarity, including transformer-coupled DC/DC converters.

 

Key electrical specifications include an operating voltage range of 10V to 30V and a maximum operating frequency of 500kHz. The device features a maximum duty cycle of 96% and offers control features such as frequency control. It operates within a temperature range of -40°C to 85°C.

 

Internally, the TL2842BP includes an undervoltage lockout (UVLO) with hysteresis and a precision trimmed reference. The output stage is a high-current totem-pole design suitable for driving N-channel MOSFETs. The controller supports various topologies including Boost, Flyback, and Forward configurations.

 

This component is available in an 8-pin PDIP package and is designed for through-hole mounting. It is specified with RoHS3 compliance and an MSL rating of 1.
