SY26023E - Synchronous Buck Converter

General Description

The SY26023E high efficiency 2.2MHz synchronous buck converter operates over a wide input voltage range of 2.5V to 5.5V, and can deliver an output current up to 3A.

It integrates a top MOSFET and a bottom MOSFET with very low RDS(ON) to minimize conduction loss.

Key Features

  • Low RDS(ON) for Internal MOSFETs: 38mΩ Top, 30mΩ Bottom.
  • Wide Input Voltage Range: 2.5V ~ 5.5V.
  • Up to 3A Output Current.
  • ±1% 0.6V Reference over Temperature from -40°C to 125°C.
  • 2.2MHz High Switching Frequency Minimizes the External Components.
  • Advanced Constant On-time and Ripple-Based Control to Achieve Fast Transient Responses.
  • Forced Continuous Conduction Mode (FCCM) Operation.
  • Internal Soft-Start Limits the Inrush Current.
  • 100% Dropout Operation.

General Description The SY26023E high efficiency 2.2MHz synchronous buck converter operates over a wide input voltage range of 2.5V to 5.5V, and can deliver an output current up to 3A. It integrates a top MOSFET and a bottom MOSFET with very low RDS(ON) to minimize conduction loss. The 2.2MHz pseudo-constant switching frequency enables using small external inductor and capacitor values. The SY26023E uses advanced constant on-time and ripple-based control strategy to achieve fast transient response. It also provides cycle-by-cycle current limit protection, output under voltage protection and over temperature protection. Only the input and output capacitors, inductor, feedback resistor divider and feedforward capacitor need to be selected for the targeted application specifications.
