The SY21525J  is a high-efficiency, dual output with 2+2, synchronous buck regulators. It integrates four synchronous buck converters, each phase is capable of delivering up to 5A continuous output current. 
The SY21525J operates over a wide input voltage range from 2.5V to 5.5V and uses instant PWM control for rapid transient response stable operation. Additionally, during startup and voltage adjustments, the device manages the output slew rate to minimize inrush current and output voltage overshoot.
The SY21525J provides undervoltage lockout (UVLO), along with overvoltage (OVP), overcurrent (OCP), and over temperature protections (OTP). In addition to the standard interrupt, chip enable, the SY21525J also supports I2C communication protocol.
The SY21525J is available in a compact WLCSP2.66× 3.89-54 package.
