High-Efficiency, 5x Output, Main Power-Supply

Controllers for Notebook Computers

General Description

Features

The MAX1533A/MAX1537A are dual step-down, switch-

mode power-supply (SMPS) controllers with synchro-

nous rectification, intended for main 5V/3.3V power

generation in battery-powered systems. Fixed-frequen-

cy operation with optimal interleaving minimizes input

ripple current from the lowest input voltages up to the

26V maximum input. Optimal 40/60 interleaving allows

the input voltage to go down to 8.3V before duty-cycle

overlap occurs, compared to 180° out-of-phase regula-

tors where the duty-cycle overlap occurs when the

input drops below 10V. Output current sensing pro-

vides accurate current limit using a sense resistor.

Alternatively, power dissipation can be reduced using

lossless inductor current sensing.

♦ Fixed-Frequency, Current-Mode Control

♦ 40/60 Optimal Interleaving

♦ Accurate Differential Current-Sense Inputs

♦ Internal 5V and 3.3V Linear Regulators with

100mA Load Capability

♦ Auxiliary 12V or Adjustable 150mA Linear

Regulator (MAX1537A Only)

♦ Dual Mode™ Feedback—3.3V/5V Fixed or

Adjustable Output (Dual Mode) Voltages

♦ 200kHz/300kHz/500kHz Switching Frequency

♦ Versatile Power-Up Sequencing

Internal 5V and 3.3V linear regulators power the

MAX1533A/MAX1537A and their gate drivers, as well as

external keep-alive loads, up to a total of 100mA. When

the main PWM regulators are in regulation, automatic

bootstrap switches bypass the internal linear regulators,

providing currents up to 200mA from each linear output.

An additional 5V to 23V adjustable internal 150mA linear

regulator is typically used with a secondary winding to

provide a 12V supply.

♦ Adjustable Overvoltage and Undervoltage

Protection

♦ 6V to 26V Input Range

♦ 2V 0.75ꢀ Reference Output

♦ Power-Good Output

♦ Soft-Shutdown

The MAX1533A/MAX1537A include on-board power-up

sequencing, a power-good (PGOOD) output, digital

soft-start, and internal soft-shutdown output discharge

that prevents negative voltages on shutdown. The

MAX1533A is available in a 32-pin 5mm x 5mm thin

QFN package, and the MAX1537A is available in a 36-

pin 6mm x 6mm thin QFN package. The exposed back-

side pad improves thermal characteristics for

demanding linear keep-alive applications.
