MAX5092/MAX5093

General Description

4V to 72V Input LDOs with Boost Preregulator

Features

The MAX5092A/MAX5092B/MAX5093A/MAX5093B low-

quiescent-current, low-dropout (LDO) regulators contain

simple boost preregulators operating at a high fre-

quency. The devices seamlessly provide a preset 3.3V

(MAX5092A/MAX5093A) or 5V (MAX5092B/MAX5093B)

LDO output voltage from a cold-crank through load-dump

(3.5V to 80V) input voltage conditions. The MAX5092_/

MAX5093_ deliver up to 250mA with excellent load and

line regulation. During normal operation, when the battery

is healthy, the boost preregulator is completely turned off,

reducing quiescent current to 65μA (typ). This makes the

devices suitable for always-on power supplies.

The buck-boost operation achieved by this combination of

LDO and boost preregulator offers the advantage of using

a single off-the-shelf inductor in place of the multiple-

winding custom magnetics needed in typical single-ended

primary inductor converter (SEPIC) and transformer-

based flyback topologies. The high operating frequency

of the boost regulator significantly reduces component

size. The MAX5092_ integrates a blocking diode to fur-

ther reduce the external component count. The boost

preregulator output voltage is preset to 7V. Both LDO and

boost output voltages are programmable using external

resistors. The boost preregulator output voltage is adjust-

able up to 11V(MAX5092_), or up to 12V (MAX5093_).

The LDO output voltage is adjustable from 1.5V to 9V

(MAX5092_) or from 1.5V to 10V (MAX5093_).

The devices feature a shutdown mode with 5μA (typ) shut-

down current, a

HOLD

input to implement a self-holding cir-

cuit, and a power-on-reset output (RESET) with an externally

programmable timeout period. Additional features include

output overload, short-circuit, and thermal protection.

The MAX5092_/MAX5093_ are available in a thermally

enhanced, 16-pin 5mm x 5mm thin QFN package and

can dissipate up to 2.7W at +70°C on a multilayer PC

board (PCB).
