Description
The 5637A is an IC chip in the RS5RJ series, which is a step-up DC/DC converter IC equipped with a voltage regulator (VR) and a voltage detector (VD) by CMOS process. It is designed with a VFM DC/DC converter, a linear regulator, and a voltage detector. The IC functions as a linear regulator when the input voltage is high, and as a step-up DC/DC converter + linear regulator when the input voltage is low. It requires external parts such as an inductor, a diode, and a capacitor. The built-in voltage detector allows for monitoring of potentials such as the output voltage of the DC/DC converters. The chip enable function can turn off internal circuits to minimize standby current, making it suitable for battery-powered and hand-held instruments.
Specifications and features
- Low Supply Current: TYP. 15µA (RS5RJ3624A : VIN=3.0V, at no load)
