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.
