Multi-Output, Low-Noise Power-Supply  
Controllers for Notebook Computers  
________________General Description  
____________________________Features  
♦ 96% Efficiency  
♦ +4.2V to +30V Input Range  
The MAX1630A–MAX1635A are buck-topology, step-  
down, switch-mode, power-supply controllers that gener-  
ate 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-com-  
pensation networks, 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  
(MAX1631A/MAX1634A)  
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  
(MAX1630A/MAX1631A/MAX1632A)  
♦ Output Undervoltage Shutdown  
(MAX1630A/MAX1631A/MAX1632A)  
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 MAX1630A–MAX1635A 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  
regulation, and the MAX1630A/MAX1632A/MAX1633A/  
MAX1635A each contain 12V/120mA linear regulators.  
The MAX1631A/MAX1634A include a secondary feed-  
back input (SECFB), plus a control pin (STEER) that  
selects which PWM (3.3V or 5V) receives the secondary  
feedback signal. SECFB provides a method for adjusting  
the secondary winding voltage regulation point with an  
external resistor-divider, and is intended to aid in creating  
auxiliary voltages other than fixed 12V.
