ADP2441 Evaluation Board

FEATURES

GENERAL DESCRIPTION

Full-featured evaluation board for the ADP2441

Configurable synchronous step down dc-dc switching

regulator

The ADP2441 evaluation board is a complete, dc-to-dc switch-

ing regulator design based on the ADP2441, a configurable, 1 A,

synchronous step-down, dc-to-dc regulator.

Operating voltage range of board: V_IN= 6 V to 36 V

Output voltage is set to 5 V or can be adjusted

Maximum load 1 A

Switching frequency set to 500 kHz or adjustable switching

frequency of 300 kHz to 1 MHz

Power saving mode at light load

Precision enable input pin

Current limit protection

Power good output

The ADP2441 is a synchronous, step-down dc-to-dc switching

regulator that uses a current mode pulse-width modulation

(PWM) control scheme at medium-to-heavy load currents for

high efficiency and smoothly transitions to a pulse skip mode

at light loads to conserve power. The power switch and

synchronous rectifier are integrated for minimal external part

count and high efficiency. The ADP2441 is optimized for

operation with small ferrite core inductors and ceramic

capacitors to deliver the maximum output power per square

millimeter of the PCB board area.

External soft start set to 6 ms or external tracking available

Board size: 53 mm × 53 mm

The ADP2441-EVALZ is available with 5 V at 1 A output,

switching frequency set to 500 kHz. If needed, the ADP2441

evaluation board configuration can be modified by changing

the values of the appropriate passive components.
