♦ High Efficiency for a Wide Range of Load Currents  
♦ 12V/150mA Flash Memory Programming Supply  
♦ 110µA Max Supply Current  
The MAX761/MAX762 s te p -up s witc hing re g ula tors  
provide high efficiency over a wide range of load currents,  
d e live ring up to 150mA. A uniq ue , c urre nt-limite d  
pulse-frequency-modulated (PFM) control scheme gives  
the devices the benefits of pulse-width-modulated (PWM)  
converters (high efficiency with heavy loads), while using  
less than 110µA of supply current (vs. 2mA to 10mA for  
PWM converters). The result is high efficiency over a wide  
range of loads.  
♦ 5µA Max Shutdown Supply Current  
♦ 2V to 16.5V Input Voltage Range  
♦ 12V (MAX761), 15V (MAX762) or Adjustable Output  
♦ Current-Limited PFM Control Scheme  
♦ 300kHz Switching Frequency  
The MAX761/MAX762 input voltage range is 2V to 16.5V.  
Output voltages are preset to 12V (MAX761) and 15V  
(MAX762), or they can be set with two external resistors.  
With a 5V input, the MAX761 guarantees a 12V, 150mA  
output. Its high efficiency, low supply current, fast start-up  
time, SHDN controlling capability, and small size make the  
MAX761 ideal for powering flash memory.

The MAX761/MAX762 have an internal 1A power MOS-  
FET, making them ideal for minimum-component, low- and  
medium-power applications. These devices use tiny exter-  
nal components, and their high switching frequencies (up  
to 300kHz) allow for small surface-mount magnetics.

For increased output drive capability or higher output volt-  
ages, use the MAX770–MAX773, which are similar in  
design to the MAX761/MAX762, but drive external power  
MOSFETs. For stepping up to 5V, see the MAX756/  
MAX757 and MAX856-MAX859 data sheets.
