SY8104I - Synchronous Step Down Regulator

Datasheet Summary

Description

The SY8104I is a high efficiency 500kHz synchronous step-down DC/DC regulator, which is capable of delivering up to 4A load current.

It can operate over a wide input voltage range from 4.2V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

Low RDS(ON) for Internal Switches (Top/Bottom): 55mΩ/36mΩ.
4.2-18V Input Voltage Range.
4A Output Current Capability.
500kHz Switching Frequency Minimize the External Components.
Stable with 22µF COUT and 0.68µH Inductor.
Instant PWM Architecture to Achieve Fast Transient Responses.
Internal Soft-Start Limits the Inrush Current.
Cycle-by-cycle Peak/Valley Current Limitation.
Hic-cup Mode Output Short Circuit Protection.
Thermal Shutdown with Aut.

SY8104I High Efficiency, Fast Response, 4.0A, 18V Input Synchronous Step Down Regulator General Description The SY8104I is a high efficiency 500kHz synchronous step-down DC/DC regulator, which is capable of delivering up to 4A load current. It can operate over a wide input voltage range from 4.2V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY8104I adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads. In addition, it operates at pseudo-constant frequency of 500kHz to minimize the size of inductor and capacitor.
