TL2842P Description

Short technical summary and product information.

The Texas Instruments TL2842P is an economy single-ended, current mode PWM controller designed for off-line and DC-to-DC converters. It operates at frequencies up to 500kHz with a voltage range of 10V to 30V and an operating temperature range of -40°C to 85°C.

 

Key features include low start-up current (<1mA), automatic feed-forward compensation, pulse-by-pulse current limiting, and enhanced load-response characteristics. It also incorporates undervoltage lockout with hysteresis and double-pulse suppression. The controller has a high-current totem-pole output and an internally trimmed bandgap reference.

 

This device is suitable for applications requiring fixed-frequency current-mode control schemes with a minimum number of external components. It is designed to be interchangeable with UC2842 and UC3842 series controllers.

 

The TL2842P is available in an 8-PDIP through-hole package. It is noted as not recommended for new designs.
