2.2MHz, 2A Buck Converters with an

Integrated High-Side Switch

General Description

Features

♦ 4.5V to 5.5V or 5.5V to 23V Input Voltage Range

♦ Output Voltage Adjustable Down to 0.6V

♦ 2A Output Current

The MAX5088/MAX5089 high-frequency, DC-DC con-

verters with an integrated n-channel power MOSFET

provide up to 2A of load current. The MAX5088

includes an internal power MOSFET to enable the

design of a nonsynchronous buck topology power sup-

ply. The MAX5089 is for the design of a synchronous

buck topology power supply. These devices operate

from a 4.5V to 5.5V or 5.5V to 23V input voltage and a

200kHz to 2.2MHz resistor-programmable switching

frequency. The voltage-mode architecture with a peak

switch current-limit scheme provides stable operation

up to a 2.2MHz switching frequency. The MAX5088

includes a clock output for driving a second DC-DC

converter 180° out-of-phase and a power-on-reset

(RESET) output. The MAX5089 includes a power-good

output and a synchronous rectifier driver to drive an

external low-side MOSFET in the buck converter config-

uration for high efficiency.

♦ Synchronous Rectifier Driver Output (MAX5089)

for Higher Efficiency

♦ Resistor-Programmable Switching Frequency

from 200kHz to 2.2MHz

♦ External Synchronization and Enable (On/Off)

Inputs

♦ Clock Output for Driving Second Converter 180°

Out-Of-Phase (MAX5089)

♦ Integrated 150mΩ High-Side n-Channel Power

MOSFET

♦ Power-On Reset Output (MAX5088)/Power-Good

Output (MAX5089)

♦ Short-Circuit Protection

The MAX5088/MAX5089 protect against overcurrent

conditions by utilizing a peak current limit as well as

overtemperature shutdown providing a very reliable

and compact power source for point-of-load regulation

applications. Additional features include synchroniza-

tion, internal digital soft-start, and an enable input. The

MAX5088/MAX5089 are available in a thermally

enhanced, space-saving 16-pin TQFN (5mm x 5mm)

package and operate over the -40°C to +125°C tem-

perature range.
