TL2845DR-8 Description

Short technical summary and product information.

The TL2845DR-8 from Texas Instruments is an economy, single-ended, current mode PWM controller. It is optimized for off-line and DC-to-DC converters, offering features necessary for fixed-frequency current-mode control schemes with minimal external components.

 

This controller operates within a voltage range of 7.6V to 30V and supports a maximum duty cycle of 48%. Its operating frequency can reach up to 500kHz. Key internal circuits include undervoltage lockout with hysteresis and double-pulse suppression. The device is housed in an 8-SOIC package and is designed for surface mount applications.

 

Features such as adjustable switching frequency, current limiting, and an error amplifier are integrated. The TL2845DR-8 is designed to be interchangeable with UC2842 and UC3842 series controllers, making it a versatile choice for power supply designs. It operates within an ambient temperature range of -40°C to 85°C.
