SP6659 - Synchronous Buck Regulator

General Description

The SP6659 is a 600mA synchronous buck regulator using a constant frequency, current mode architecture.

The output voltage can be programmed using an external resistor divider.

The 2.5V to 5.5V input voltage range is ideal for portable applications that use a Li-Ion battery.

Key Features

  • 94% Efficiency Possible.
  • 600mA Output Current at VIN = 3.6V.
  • 2.5V to 5.5V Input Voltage Range.
  • 1.5MHz constant frequency operation.
  • No Schottky Diode Required.
  • Output Voltages as low as 0.6V.
  • Slope Compensated Current Mode Operation for Excellent Line and Load Transient Response.
  • 100 % Duty Cycle in LDO Mode.
