MAX15014–MAX15017

1A, 4.5V to 40V Input Buck Converters with

50mA Auxiliary LDO Regulators

General Description

The MAX15014–MAX15017 combine a step-down DC-DC

converter and a 50mA, low-quiescent-current low-dropout

(LDO) regulator. The LDO regulator is ideal for powering

always-on circuitry. The DC-DC converter input voltage

range is 4.5V to 40V for the MAX15015/MAX15016, and

7.5V to 40V for the MAX15014/MAX15017.

The DC-DC converter output is adjustable from 1.26V

to 32V and can deliver up to 1A of load current. These

devices utilize a feed-forward voltage-mode-control

scheme for good noise immunity in the high-voltage

switching environment and offer external compensation

allowing for maximum flexibility with a wide selection

of inductor values and capacitor types. The switching

frequency is internally fixed at 135kHz and 500kHz,

depending on the version chosen. Moreover, the switch-

ing frequency can be synchronized to an external clock

signal through the SYNC input. Light-load efficiency

is improved by automatically switching to a pulse-skip

mode. The soft-start time is adjustable with an external

capacitor. The DC-DC converter can be disabled inde-

pendent of the LDO, thus reducing the quiescent current

to 47μA (typ).

The LDO linear regulators operate from 5V to 40V and

deliver a guaranteed 50mA load current. The devices

feature a preset output voltage of 5V (MAX1501_A) or

3.3V (MAX1501_B). Alternatively, the output voltage

can be adjusted from 1.5V to 11V by using an external

resistive divider. The LDO section also features a

RESET

output with adjustable timeout period.

Protection features include cycle-by-cycle current limit,

hiccup-mode output short-circuit protection, and thermal

shutdown. All devices are available in a space-saving,

high-power (2.86W), 36-pin TQFN package and are rated

for operation over the -40°C to +125°C automotive tem-

perature range.
