請推薦DC/DC降壓芯片
本人正設(shè)計一款12轉(zhuǎn)05輸出的200MA的電源,由于要求封裝小,現(xiàn)請朋友們推薦一款降壓IC,要求輸出外接電容小,就可達到很低的紋波,盡量IC里已內(nèi)置MOS管,這樣體積就小,(33063輸出要很大的電容,所以不選它了)IC溫度一定要達到-40~85度,主要是準軍品的產(chǎn)品.

The ACT4060 is a current-mode step-down
DC-DC converter that generates up to 2A output
current at 410kHz switching frequency. The
device utilizes Active-Semi’s proprietary
ISOBCD20 process for operation with input
voltage up to 20V.
Consuming only 8µA in shutdown mode, the
ACT4060 is highly efficient with peak efficiency
at 95% when in operation. Protection features
include cycle-by-cycle current limit, thermal
shutdown, and frequency fold back at short
circuit.
