ADP3025 Datasheet High Efficiency Dual Output Power Supply Controller

Manufacturer: Analog Devices

Overview: High Efficiency Dual Output Power Supply Controller ADP3025.

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.

The ADP3025 provides accurate and reliable short-circuit protection by using an internal current sense circuit that reduces cost and increases overall efficiency.

Key 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) Prog.
