60mA, 5.0V, Buck/Boost Charge Pump

in ThinSOT-23 and ThinQFN

FEATURES

DESCRIPTION

•

Wide Input Range: 1.8V to 5.5V

Automatic Step-Up/Step-Down Operation

Low Input Current Ripple

The REG710 is

a switched capacitor voltage

converter that produces a regulated, low-ripple output

voltage from an unregulated input voltage. A wide

input supply voltage of 1.8V to 5.5V makes the

REG710 ideal for a variety of battery sources, such

as single-cell Li-Ion, or two- and three-cell nickel- or

alkaline-based chemistries.

•

Low Output Voltage Ripple

Minimum Number of External

Components—No Inductors

•

1MHz Internal Oscillator Allows Small

Capacitors

The input voltage may vary above and below the

output voltage and the output remains in regulation. It

works equally well for step-up or step-down

applications without the need for an inductor,

providing low EMI dc/dc conversion. The high

switching frequency allows the use of small

surface-mount capacitors, saving board space and

reducing cost. The REG710 is thermally protected

and current limited, protecting the load and the

regulator during fault conditions. Typical ground pin

current (quiescent current) is 65µA with no load, and

less than 1µA in shutdown mode.
