The TL2844D from Texas Instruments is an economy single-ended, current mode PWM controller suitable for off-line and DC-to-DC converter applications. It features a 500kHz operating frequency and a maximum duty cycle of 48%.
Key internal circuits include an undervoltage lockout (UVLO) with hysteresis, a low start-up current of less than 1mA, and automatic feed-forward compensation. It also provides pulse-by-pulse current limiting, enhanced load-response characteristics, and double-pulse suppression. The device includes a high-current totem-pole output stage, suitable for driving N-channel MOSFETs, and an internally trimmed bandgap reference.
This controller is designed for a voltage range of 10V to 30V and operates within an ambient temperature range of -40°C to 85°C. The TL2844D is packaged in a 14-SOIC (Surface Mount) package and is designed to be interchangeable with the UC2842 and UC3842 series.
Its features make it a versatile component for implementing fixed-frequency current-mode control schemes with a minimal number of external components.
