SY8208AQNC Datasheet Synchronous Step-down Regulator

Manufacturer: Silergy

Overview: 昱灿电子 www.szyucan.com Application Notes: AN_SY8208A High Efficiency Fast Response 8A Continuous, 16A Peak, 28V Input Synchronous Step Down Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The SY8208A develops a high efficiency synchronous step-down DC-DC regulator capable of delivering 8A continuous, 16A peak current.

The SY8208A operates over a wide input voltage range from 4V to 28V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

The SY8208A adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads.

Key Features

  • Low RDS(ON) for internal switches (top/bottom): 20/10 mΩ.
  • Wide input voltage range: 4-28V.
  • Instant PWM architecture to achieve fast transient responses.
  • Internal 400uS softstart limits the inrush current.
  • Pseudo-constant frequency: 800kHz.
  • 8A continuous/16A peak output current capability.
  • ±1.5% 0.6V reference.
  • Programmable peak current limit.
  • Power good indicator.
  • Output discharge function.
  • Short.
