General Description
RY1505 is a highly integrated power management IC (PMIC) designed to minimize power consumption in
consumer and multimedia applications. It provides a complete system power management solution, the RY1505
integrates 3-ch synchronous buck converter, 2-ch LDO,1-ch power on reset. The converters are optimized for high
efficiency (greater than 92%) and feature integrated low impedance FETs. The RY1505 is available in a 28 pins
QFN 4×4 package.
