90% Efficiency for 10mA to 1A Load Currents  
Up to 15W Output Power  
The MAX770–MAX773 step-up switching controllers pro-  
vid e 90% e ffic ie nc y ove r a 10mA to 1A loa d . A  
unique current-limited pulse-frequency-modulation (PFM)  
control scheme gives these devices the benefits of  
pulse-width-modulation (PWM) converters (high efficiency  
at heavy loads), while using less than 110µA of supply  
current (vs. 2mA to 10mA for PWM converters).  
110µA Max Supply Current  
5µA Max Shutdown Current  
2V to 16.5V Input Range  
These ICs use tiny external components. Their high  
switching frequencies (up to 300kHz) allow surface-  
mount magnetics of 5mm height and 9mm diameter.  
(MAX770/MAX771/MAX772)  
Internal Shunt Regulator for High Input Voltages  
(MAX773)  
The MAX770/MAX771/MAX772 accept input voltages  
from 2V to 16.5V. Output voltages are preset at 5V,  
(MAX770), 12V (MAX771), and 15V (MAX772); they can  
also be adjusted using two resistors.  
Preset or Adjustable Output Voltages  
MAX770: 5V or Adjustable  
MAX771: 12V or Adjustable  
The MAX773 accepts inputs from 3V to 16.5V. For a wider  
input range, it features an internal shunt regulator that  
allows unlimited higher input voltages. The MAX773s out-  
put can be set to 5V, 12V, or 15V, or it can be adjusted  
with two resistors.  
MAX772: 15V or Adjustable  
MAX773: 5V, 12V, 15V, or Adjustable  
Current-Limited PFM Control Scheme  
300kHz Switching Frequency  
The MAX770–MAX773 drive external N-channel MOSFET  
switches, allowing them to power loads up to 15W. If less  
p owe r is re q uire d , us e the MAX756/MAX757 or  
MAX761/MAX762 step-up switching regulators with on-  
board MOSFETs.
