The CS5141X products are 1.5 A buck regulator ICs. These devices are fixed–frequency operating at 260 kHz and 520 kHz. The regulators use the V2 control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high–speed logic
The CS5141X products are 1.5 A buck regulator ICs that operate at fixed frequencies of 260 kHz or 520 kHz. These devices utilize V2 control architecture to provide unmatched transient response, the best overall regulation, and the simplest loop compensation for high-speed logic applications. They accommodate input voltages from 4.5 V to 40 V and feature protection circuitry including thermal shutdown, cycle-by-cycle current limiting, and frequency foldback.
