The MAX1626/MAX1627 step-down DC-DC switching

controllers provide high efficiency over loads ranging

from 1mA to more than 2A. A unique current-limited,

p uls e -fre q ue nc y-mod ula te d (PFM) c ontrol s c he me

operates with up to a 100% duty cycle, resulting in very

low dropout voltages. This control scheme eliminates

minimum load requirements and reduces the supply

current under light loads to 90µA (versus 2mA to 10mA

for common pulse-width modulation controllers).

♦ Low Dropout Voltage

♦ 100% Maximum Duty Cycle

♦ Soft-Start Limits Start-Up Current

♦ Efficiency >90% (3mA to 2A Loads)

♦ Output Power >12.5W

♦ 90µA Max Quiescent Current

♦ 1µA Max Shutdown Current

♦ Up to 300kHz Switching Frequency

♦ 16.5V Max Input Voltage

These step-down controllers drive an external P-chan-

nel MOSFET, allowing design flexibility for applications

to 12W or higher. Soft-start reduces current surges dur-

ing start-up. A high switching frequency (up to 300kHz)

and operation in continuous-conduction mode allow the

use of tiny surface-mount inductors. Output capacitor

requirements are also reduced, minimizing PC board

area and system costs.

♦ Output Voltage: 5V/3.3V (MAX1626)

Adjustable (MAX1627)

♦ Current-Limited Control Scheme

The outp ut volta g e is p re s e t a t 5V or 3.3V for the

MAX1626 and adjustable for the MAX1627. Input volt-

ages can be up to 16.5V. The MAX1626/MAX1627 are

functional upgrades for the MAX1649/MAX1651.
