AIC1653中文资料Micropower Inverting DC/DC Converter in SOT23-5数据手册AIC规格书

描述 Description

The AIC1653 is a micropower inverting DC/DC converter in SOT23-5 package. It is designed for power systems with a 100mA current limit and an input voltage ranging from 1.8V to 10V. Besides, AIC1653 features a quiescent current of only 15uA at no load, which further reduces to 0.5uA when shutdown.

The schemes of current limited and fixed off-time control conserve operating current, resulting in high efficiency over a broad range of load current. In addition, the 30V switch of AIC1653 allows high voltage outputs up to -28V, which is easily generated without the use of costly transformers. The AIC1653s low off-time of 400ns permits the use of tiny, low profile inductors and capacitors to minimize footprint and cost in space-conscious portable applications.
