SY8113C - Synchronous Step Down Regulator

Description

The SY8113C is a high efficiency 1MHz synchronous step-down DC-DC converter capable of delivering 3A current.

The SY8113C operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

  • low RDS(ON) for internal switches (top/bottom): 80mΩ/40mΩ.
  • 4.5-18V input voltage range.
  • 3A output current capability.
  • 1MHz switching frequency.
  • Instant PWM architecture to achieve fast transient responses.
  • Internal softstart limits the inrush current.
  • ±1.5% 0.6V reference.
  • TSOT23-6 package.

Application Notes: AN_SY8113C High Efficiency, 1MHz, 3A, 18V Input Synchronous Step Down Regulator General Description The SY8113C is a high efficiency 1MHz synchronous step-down DC-DC converter capable of delivering 3A current. The SY8113C operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz switching frequency. It adopts the instant PWM architecture to achieve fast transient responses for high step down applications.
