19-3944; Rev 1; 5/06  
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.  
♦ Thermal-Shutdown Protection  
♦ Thermally Enhanced 16-Pin TQFN Package
