General Description

The ADP2503/ADP2504 are high efficiency, low quiescent current step-up/step-down dc-to-dc converters that can operate at input voltages greater than, less than, or equal to the regulated output voltage.

The power switches and synchronous rectifiers are internal to minimize external device count.

At high load currents, the ADP2503/ADP2504 use a current-mode, fixed frequency pulsewidth modulation (PWM) control scheme for optimal stability and transient response.
