Overview

Analog Devices ADP244x Synchronous, Step-down, DC-to-DC Switching Regulators feature an integrated 98m, high-side power metal oxide semiconductor field effect transistor (MOSFET) and a 35m, synchronous rectifier MOSFET. The ADP244x regulators operate from a 4.5V to 36V input voltage range. Designers can adjust the output voltage down to 0.6V as well as program the switching frequency from 200kHz to 1.8MHz. These high-power efficiency regulators deliver up to 3A of continuous current. The ADP244x's fast 50ns minimum on-time enables the regulators to convert high-input voltage to low-output voltage at high frequency. The regulators use an emulated current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. ADP244x's synchronization function enables the switching frequency to be synchronized with an external clock to minimize the system noise. Simple, reliable power sequencing is provided through the regulator's power-good output and precision-enable input. The integrated design of the ADP244x Switching Regulators provide a high-efficiency power solution with up to �1 output accuracy in 4mm x 4mm compact package.
