0.3µA IQ低静态电流 300mA带同步整流器功能的升降压DC/DC转换器
-
概述
The RP604 is a buck-boost converter featuring a minimum supply current and a high efficiency at low-load. The device operates at the low operating quiescent current (IQ = 0.3 µA) to make the most of battery life for the battery driver operated intermittently.
特点
- The low supply current (IQ = 0.3 μA) can achieve making battery life longer and battery’s size-reduction.
- Wide range of input voltage (1.8 V to 5.5 V) can support for every batteries from a coin-type battery to a USB port.
- Selectable package: WLCSP-20-P2 or DFN(PL)2730-12
