POWSUM1771
5,00 €

General Description
The MAX1771 step-up switching controller provides 90% efficiency over a 30mA to 2A load. A unique cur rent-limited pulse-frequency-modulation (PFM) control scheme gives this device 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).

Features
♦ 90% Efficiency for 30mA to 2A Load Currents
♦ Up to 24W Output Power
♦ 110µA Max Supply Current
♦ 5µA Max Shutdown Current
♦ 2V to 16.5V Input Range
♦ Preset 12V or Adjustable Output Voltage
♦ Current-Limited PFM Control Scheme
♦ Up to 300kHz Switching Frequency
