CS51411-D中文资料安森美半导体数据手册PDF规格书

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 todays high-speed logic. These products accommodate input voltages from 4.5 V to 40 V.
