♦ 96% Efficiency

♦ +4.2V to +30V Input Range

The MAX1630–MAX1635 are buck-topology, step-down,

switch-mode, power-supply controllers that generate

logic-supply voltages in battery-powered systems. These

high-performance, dual/triple-output devices include on-

board power-up sequencing, power-good signaling with

delay, digital soft-start, secondary winding control, low-

dropout circuitry, internal frequency-compensation net-

works, and automatic bootstrapping.

♦ 2.5V to 5.5V Dual Adjustable Outputs

♦ Selectable 3.3V and 5V Fixed or Adjustable

Outputs (Dual Mode™)

♦ 12V Linear Regulator

♦ Adjustable Secondary Feedback

(MAX1631/MAX1634)

Up to 96% efficiency is achieved through synchronous

rectification and Maxim’s proprietary Idle Mode™ control

scheme. Efficiency is greater than 80% over a 1000:1

load-current range, which extends battery life in system-

suspend or standby mode. Excellent dynamic response

corrects output load transients caused by the latest

dynamic-clock CPUs within five 300kHz clock cycles.

Strong 1A on-board gate drivers ensure fast external

N-channel MOSFET switching.

♦ 5V/50mA Linear Regulator Output

♦ Precision 2.5V Reference Output

♦ Programmable Power-Up Sequencing

♦ Power-Good (RESET) Output

♦ Output Overvoltage Protection

(MAX1630/MAX1631/MAX1632)

♦ Output Undervoltage Shutdown

(MAX1630/MAX1631/MAX1632)

These devices feature a logic-controlled and synchroniz-

able, fixed-frequency, pulse-width-modulation (PWM)

operating mode. This reduces noise and RF interference

in sensitive mobile communications and pen-entry appli-

cations. Asserting the SKIP pin enables fixed-frequency

mode, for lowest noise under all load conditions.

♦ 200kHz/300kHz Low-Noise, Fixed-Frequency

Operation

♦ Low-Dropout, 99% Duty-Factor Operation

♦ 2.5mW Typical Quiescent Power (+12V input, both

SMPSs on)

♦ 4µA Typical Shutdown Current

♦ 28-Pin SSOP Package

The MAX1630–MAX1635 include two PWM regulators,

adjustable from 2.5V to 5.5V with fixed 5.0V and 3.3V

modes. All these devices include secondary feedback

re g ula tion, a nd the MAX1630/MAX1632/MAX1633/

MAX1635 each contain 12V/120mA linear regulators. The

MAX1631/MAX1634 include a secondary feedback input

(SECFB), plus a control pin (STEER) that selects which

PWM (3.3V or 5V) receives the secondary feedback sig-

nal. SECFB provides a method for adjusting the sec -

ondary winding voltage regulation point with an external

resistor divider, and is intended to aid in creating auxiliary

voltages other than fixed 12V.
