Low IQ Inverting DC-to-DC Controllers  
General Description  
Features  
The MAX774/MAX775/MAX776 inverting switching  
regulators deliver high efficiency over three decades of  
load current. A unique current-limited, pulse-  
frequency modulated (PFM) control scheme provides  
the benefits of pulse-width modulation (high efficiency  
with heavy loads), while using less than 100µA of supply  
current (vs. 2mA to 10mA for PWM converters). The result  
is high efficiency over a wide range of loads.  
ꢀ 85% Efficiency for 5mA to 1A Load Currents  
ꢀ Up to 5W Output Power  
ꢀ 100µA (max) Supply Current  
ꢀ 5µA (max) Shutdown Current  
ꢀ 3V to 16.5V Input Range  
ꢀ -5V (MAX774), -12V (MAX775), -15V (MAX776),  
These ICs also use tiny external components; their high  
switching frequency (up to 300kHz) allows for less than  
5mm diameter surface-mount magnetics.  
or Adjustable Output Voltage  
ꢀ Current-Limited PFM Control Scheme  
ꢀ 300kHz Switching Frequency  
The MAX774/MAX775/MAX776 accept input voltages from  
3V to 16.5V, and have preset output voltages of  
-5V, -12V, and -15V, respectively. Or, the output voltage  
can be user-adjusted with two resistors. Maximum  
VIN - VOUT differential voltage is limited only by the break-  
down voltage of the chosen external switch transistor.

These inverters use external P-channel MOSFET switches,  
allowing them to power loads up to 5W. If less power is  
required, use the MAX764/MAX765/MAX766 inverting  
switching regulators with on-board MOSFETs.
