MAX1649EPA規(guī)格書詳情

General Description

The MAX1649/MAX1651 BiCMOS, step-down, DC-DC switching controllers provide high efficiency over loads ranging from 1mA to more than 2.5A. A unique, current limited pulse-frequency-modulated (PFM) control scheme gives these devices the benefits of pulse-width-modulation (PWM) converters (high efficiency at heavy loads), while using only 100μA of supply current (vs. 2mA to 10mA for PWM converters). Dropout performance down to 300mV is provided by a high switch duty cycle (96.5) and a low current-sense threshold (110mV).

Features

? More than 90 Efficiency (10mA to 1.5A Loads)

? More than 12.5W Output Power

? Less than 0.3V Dropout Voltage at 500mA

? 100μA Max Quiescent Supply Current

? 5μA Max Shutdown Supply Current

? 16V Max Input Voltage

? 5V (MAX1649), 3.3V (MAX1651), or Adjustable

Output Voltage

? Current-Limited Control Scheme

? Up to 300kHz Switching Frequency

? Up to 96.5 Duty Cycle
