4V to 72V Input LDOs with Boost Preregulator

2/MAX5093

General Description

Features

♦ Wide Operating Input Voltage Range: 3.5V to 72V

The MAX5092A/MAX5092B/MAX5093A/MAX5093B low-

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

simple boost preregulators operating at a high frequency.

The devices seamlessly provide a preset 3.3V

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

LDO output voltage from an automotive cold-crank

through load-dump (3.5V to 80V) input voltage condi-

tions. The MAX5092_/MAX5093_ deliver up to 250mA

with excellent load and line regulation. During normal

operation, when the battery is healthy, the boost preregu-

lator is completely turned off, reducing quiescent current

to 65µA (typ). This makes the devices suitable for

always-on power supplies.

with a 4V Startup Voltage

♦ LDO Output Regulates to 5V Seamlessly from an

Input Voltage of 3.5V to 72V

♦ Up to 250mA Output Current

♦ Preset 3.3V, 5V, or Externally Programmable LDO

Output Voltage from 1.5V to 9V (MAX5092_) or

from 1.5V to 10V (MAX5093_)

♦ Preset 7V or Externally Programmable Boost

Output Voltage Up to 11V (MAX5092_) or Up to

12V (MAX5093_)

♦ 65µA Quiescent Current in LDO Mode (V ≥8V)

♦ 5µA Shutdown Current

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 mul-

tiple-winding custom magnetics needed in typical sin-

gle-ended primary inductor converter (SEPIC) and

transformer-based flyback topologies. The high operat-

ing frequency of the boost regulator significantly

reduces component size. The MAX5092_ integrates a

blocking diode to further reduce the external compo-

nent count. The boost preregulator output voltage is

preset to 7V. Both LDO and boost output voltages are

programmable using external resistors. The boost pre-

regulator output voltage is adjustable 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_).

♦ Power-On Reset (RESET) with Programmable

Timeout Period

♦ Output Short-Circuit and Thermal Protection

♦ TQFN Package Capable of Dissipating Up to 2.7W

at +70°C

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

shutdown current, a HOLD input to implement a self-hold-

ing circuit, and a power-on-reset output (RESET) with an

externally programmable timeout period. Additional fea-

tures include output overload, short-circuit, and thermal

protection.
