Low-Cost, High-Frequency, Current-Mode PWM
General Description
The MAX1953/MAX1954/MAX1957 is a family of versa-
tile, economical, synchronous current-mode, pulse-width
modulation (PWM) buck controllers. These step-down
controllers are targeted for applications where cost and
size are critical.
The MAX1953 operates at a fixed 1MHz switching fre-
quency, thus significantly reducing external component
size and cost. Additionally, excellent transient response
is obtained using less output capacitance. The MAX1953
operates from low 3V to 5.5V input voltage and can sup-
ply up to 10A of output current. Selectable current limit is
provided to tailor to the external MOSFETs’ on-resistance
for optimum cost and performance. The output voltage is
adjustable from 0.8V to 0.86V
.
IN
With the MAX1954, the drain-voltage range on the high-
side FET is 3V to 13.2V and is independent of the supply
voltage. It operates at a fixed 300kHz switching frequen-
cy and can be used to provide up to 25A of output cur-
rent with high efficiency. The output voltage is adjustable
from 0.8V to 0.86V
.
HSD
The MAX1957 features a tracking output voltage range of
0.4V to 0.86V
and is capable of sourcing or sinking
IN
current for applications such as DDR bus termination
and PowerPC™/ASIC/DSP core supplies. The MAX1957
operates from a 3V to 5.5V input voltage and at a fixed
300kHz switching frequency.
The MAX1953/MAX1954/MAX1957 provide a COMP pin
that can be pulled low to shut down the converter in
addition to providing compensation to the error amplifier.
An input undervoltage lockout (ULVO) is provided to
ensure proper operation under power-sag conditions to
prevent the external power MOSFETs from overheating.
Internal digital soft-start is included to reduce inrush cur-
rent. The MAX1953/MAX1954/MAX1957 are available in
tiny 10-pin µMAX packages.
