SY21264A Datasheet 1mhz Step-up Regulator

Manufacturer: Silergy

Overview: SY21264A High Efficiency 6V, 4A, 1MHz Step-Up Regulator General.

General Description

The SY21264A high efficiency step-up regulator operates using current mode control, and can deliver 4A current over a wide input voltage range from 2V to 6V.

It integrates an N-channel MOSFET with low 90mΩ RDS(ON) to minimize conduction loss.

The 1MHz switching frequency and internal pensation reduce external inductor and capacitor sizes, and the built-in internal soft-start circuitry minimizes inrush current at startup.

Key Features

  • 2V to 6V Input Voltage Range.
  • Up to 6V Output Voltage.
  • Low RDS(ON) for Internal N-Channel MOSFET: 90mΩ Typical.

  • Minimum Off-Time: 100ns Typical.
  • Internal 4A Switch.
  • Internal Soft-Start Limits Inrush Current.
  • ±2% 0.6V Reference.
  • Overtemperature Protection.
  • Overcurrent Protection.
  • RoHS-Compliant and Halogen-Free.
  • Compact DFN3mmx3mm-10 Package.
