SP6659 Datasheet (Sipex Corporation) - Synchronous Buck Regulator

SP6659, Synchronous Buck Regulator

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.

Switching frequency is
