Step-Down Converters:

management (PWM) ICs for portable applications.

–

Both devices combine a single step-down converter

range of load currents. For low-noise applications, the

–

600-mA or 1-A (TPS650061) Output Current

devices can be forced into fixed-frequency PWM

•

Low Dropouts (LDOs):

through a pin. The step-down converter is small

because of its small inductor and capacitors. The

Adjustable Output Voltage

for sequencing. The LDOs can supply 300 mA and

Up to 300-mA Output Current

operate with an input voltage range from 1.6 V to 6 V.

A step-down converter or main battery can power the
