The L296 is a high current switching regulator produced by Linear Technology, which can output 4A of current, with an output voltage range from 5.1V to 40V, supporting 0 to 100% duty cycle, precision of ±2%, switching frequency up to 200KHz, efficiency up to 90%, very few external components, soft start, reset output, external programmable limiting current (L296P), control circuit for Crowbar SCR, input for remote inhibit and synchronous PWM, and thermal shutdown.
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.
