请推荐DC/DC降压芯片
本人正设计一款12转05输出的200MA的电源,由于要求封装小,现请朋友们推荐一款降压IC,要求输出外接电容小,就可达到很低的纹波,尽量IC里已内置MOS管,这样体积就小,(33063输出要很大的电容,所以不选它了)IC温度一定要达到-40~85度,主要是准军品的产品.

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.
