The TL2845D-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.
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 supports multiple topologies including Boost, Flyback, and Forward. The controller features adjustable switching frequency, current limiting, an error amplifier, and fixed frequency operation.
This device is housed in an 8-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C (TA). The TL2845D-8 is noted for its low start-up current, automatic feed-forward compensation, pulse-by-pulse current limiting, and enhanced load-response characteristics. It also includes undervoltage lockout with hysteresis and double-pulse suppression.
Internally trimmed bandgap reference and a high-current totem-pole output are also featured. The TL284x series, including the TL2845D-8, is designed to be interchangeable with UC2842 and UC3842 series controllers.
