SP6655 Datasheet High Efficiency 400ma Synchronous Buck Regulator

Manufacturer: Exar (now MaxLinear)

Overview: SP6655 High Efficiency 400mA Synchronous Buck Regulator December.

General Description

The SP6655 is a 400mA synchronous buck regulator which is ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input.

The SP6655’s proprietary control loop, 20μA light load quiescent current, and 0.3Ω power switches provide excellent efficiency across a wide range of output currents.

As the input battery supply decreases towards the output voltage, the SP6655 seamlessly transitions into 100% duty ratio operation, further extending useful battery life.

Key Features

  • include programmable under voltage lockout and low battery detection, externally programmed output voltage down to 1.0V, logic level shutdown control, and 140°C over temperature shutdown.
