Описание

The MAX1763EEE+ is a high power, low noise step-up DC to DC converter in 16 pin QSOP package. It is intended for use in battery powered wireless applications. This device maintains exceptionally low quiescent supply current (110µA) despite its high 1MHz operating frequency. Small external components and tiny package make this device an excellent choice for small hand held applications that require longest possible battery life. The MAX1763 uses synchronous rectified PWM boost topology to generate 2.5V to 5.5V outputs from wide range of input sources such as one to three alkaline or NiCd/NiMH cells or single Li-Ion (Li+) cell. The Maxim's Idle Mode circuitry significantly improves efficiency at light load currents while smoothly transitioning to fixed frequency PWM operation at higher load currents to maintain excellent full load efficiency. The MAX1763 may also be synchronized to an external clock to protect sensitive frequency bands in communications equipment.
