Part Name(s) : AIC1653 AIC1653CV AIC1653CVBG AIC1653CVTR AIC
Analog Intergrations
Description : Micropower INVERTING DC/DC CONVERTER in SOT-23-5 View

DESCRIPTION
The AIC1653 is a micropower INVERTING DC/DC CONVERTER in 5-lead SOT-23 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 15µA at no load, which further reduces to 0.5µA 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 AIC1653’s 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.
