STMicroelectronics L296/L296P High Current Switching Regulators Datasheet
The L296 and L296P are monolithic stepdown power switching regulators that deliver 4 A of output current with a voltage range from 5.1 V to 40 V. These devices operate with a duty cycle range of 0 to 100 % and feature a switching frequency up to 200 KHz, allowing for very high efficiency up to 90 % with very few external components.
Key features include a precise on-chip reference, soft start, reset output for microprocessors, and thermal shutdown. The L296P variant includes an external programmable limiting current function. Both devices provide a control circuit for a crowbar SCR, an input for remote inhibit, and a synchronization PWM input for multichip configurations.
