General Description
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.
FEATUREs
♦ 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), or Adjustable Output Voltage
♦ Current-Limited PFM Control Scheme
♦ 300kHz Switching Frequency
