TL3845BD Description

Short technical summary and product information.

The TL3845BD from Texas Instruments is a high-performance current-mode PWM controller designed for off-line and DC-to-DC fixed-frequency current-mode control schemes. It features a supply voltage range of 7.6V to 30V and operates at a switching frequency of 100kHz with a maximum duty cycle of 48%.

 

This controller integrates essential features such as an undervoltage lockout (UVLO) and a precision reference. Its totem-pole output stage is suitable for driving N-channel MOSFETs. The device supports multiple topologies including Boost, Flyback, and Forward converters, making it versatile for various power supply designs.

 

The TL3845BD is housed in a 14-SOIC surface-mount package, facilitating integration into compact electronic systems. It is characterized for operation within an ambient temperature range of 0°C to 70°C.

 

Key electrical characteristics include a low start-up current of less than 0.5mA and trimmed oscillator discharge current. The device also offers features like latching PWM for cycle-by-cycle current limiting and double-pulse suppression.
