TL2845P Description

Short technical summary and product information.

The Texas Instruments TL2845P is an integrated circuit designed for implementing fixed-frequency current-mode control schemes in off-line and DC-to-DC converters. This controller supports multiple topologies including Boost, Flyback, and Forward configurations.

 

Key electrical specifications include an operating voltage range of 7.6V to 30V and a maximum duty cycle of 48%. It operates at frequencies up to 500kHz and features adjustable switching frequency, current limiting, and an error amplifier with low output resistance. The device includes undervoltage lockout with hysteresis and double-pulse suppression.

 

Packaged in an 8-pin PDIP through-hole configuration, the TL2845P is optimized for ease of integration into various power supply designs. Its operating temperature range is -40°C to 85°C.

 

This controller is designed to be interchangeable with UC2842 and UC3842 series, offering features necessary for efficient power management with a minimal number of external components.
