____________________________Fe a t u re s

The MAX1652–MAX1655 are high-efficiency, pulse-

width-modulated (PWM), step-down DC-DC controllers

in small QSOP packages. The MAX1653/MAX1655 also

c ome in 16-p in na rrow SO p a c ka g e s tha t a re p in-

compatible upgrades to the popular MAX797. Improve-

ments include higher duty-cycle operation for better

dropout, lower quiescent supply currents for better

light-load efficiency, and an output voltage down to 1V

(MAX1655).

♦ 96% Efficiency

♦ Small, 16-Pin QSOP Package

(half the size of a 16-pin narrow SO)

♦ Pin-Compatible with MAX797 (MAX1653/MAX1655)

♦ Output Voltage Down to 1V (MAX1655)

♦ 4.5V to 30V Input Range

♦ 99% Duty Cycle for Lower Dropout

♦ 170µA Quiescent Supply Current

The MAX1652–MAX1655 achieve up to 96% efficiency

and deliver up to 10A using a unique Idle Mode™ syn-

chronous-rectified PWM control scheme. These devices

automatically switch between PWM operation at heavy

loads and pulse-frequency-modulated (PFM) operation

at light loads to optimize efficiency over the entire out-

put current range. The MAX1653/MAX1655 also feature

logic-controlled, forced PWM operation for noise-sensi-

tive applications.

♦ 3µA Logic-Controlled Shutdown

♦ Dual, N-Channel, Synchronous-Rectified Control

♦ Fixed 150kHz/300kHz PWM Switching,

or Synchronized from 190kHz to 340kHz

♦ Programmable Soft Start

♦ Low-Cost Secondary Outputs (MAX1652/MAX1654)

All devices operate with a selectable 150kHz/300kHz

switching frequency, which can also be synchronized

to an external clock signal. Both external power switch-

es are inexpensive N-channel MOSFETs, which provide

low resistance while saving space and reducing cost.

The MAX1652 and MAX1654 have an additional feed-

back pin that permits regulation of a low-cost second

outp ut ta p p e d from a tra ns forme r wind ing . The

The MAX1652–MAX1655 have a 4.5V to 30V input volt-

age range. The MAX1652/MAX1653/MAX1654’s output

range is 2.5V to 5.5V while the MAX1655’s output range

extends down to 1V. An evaluation kit (MAX1653EVKIT)

is available to speed designs.
