GENERAL DESCRIPTION
The ADP3025 is a highly efficient, dual synchronous buck switching regulator controller optimized for converting a battery or adapter input into the supply voltage required in portable products and industrial systems. The oscillator frequency can be programmed for 200 kHz or 300 kHz operation, or can be synchronized to an external clock signal of up to 350 kHz.

FEATURES
   Wide input voltage range: 5.5 V to 25 V
   High conversion efficiency > 96%
   Integrated current sense—no external resistor required
   Low shutdown current: 19 µA (typical)
   Voltage mode PWM with input feed-forward for fast line
   transient response
   Dual synchronous buck controllers
   Built-in gate drive boost circuit for driving external high-side
   N-channel MOSFET
   2 independently programmable output voltages:
   Fixed 3.3 V or adjustable (800 mV to 6.0 V)
   Fixed 5 V or adjustable (800 mV to 6.0 V)
   Programmable PWM frequency
   Integrated linear regulator controller
   Extensive circuit protection functions

APPLICATIONS
   Portable instruments
   General-purpose dc-to-dc converters
