SY21565TTC is a wide input voltage range, high efficiency PMIC for USB power delivery applications. The device integrates a 5A buck regulator, an external P-MOSFET driver and an external NMOS driver to achieve power path control.
The buck regulator adopts fixed switching frequency peak current mode control. The output voltage can be either configured by the I2C interface from 3.0V to 21V in 200mV per step or programmed by the FB pin. With high switching frequency and low RDS (ON) power switches, the device is able to achieve both small size and high efficiency solution.
The device integrates an I2C compatible interface for mode selecting, output voltage setting, frequency setting, protection setting, etc.
The device is available in compact QFN3x3-19.
