TL2845BD Description

Short technical summary and product information.

The TL2845BD is a current-mode Pulse Width Modulation (PWM) controller IC from Texas Instruments, designed for efficient implementation of off-line or DC-to-DC fixed-frequency switching power supplies. It supports multiple topologies including Boost, Flyback, and Forward configurations.

 

Key electrical features include a wide operating voltage range of 7.6V to 30V and a maximum operating frequency of up to 500kHz. The device offers a maximum duty cycle of 48% and operates within a temperature range of -40°C to 85°C. It features a low start-up current of less than 0.5mA and trimmed oscillator discharge current.

 

This controller is housed in a 14-SOIC package, suitable for surface mount applications. The output stage is designed to drive N-channel MOSFETs. Its internal circuitry includes undervoltage lockout (UVLO) with specific thresholds and a latched PWM for cycle-by-cycle current limiting.

 

The TL2845BD is suitable for various switching regulator applications requiring precise current control and high efficiency.
