The MAX1700/MAX1701 are high-efficiency, low-noise, step-up DC-DC converters intended for use in battery-powered wireless applications. They use a synchronous-rectified pulse-width-modulation (PWM) boost topology to generate 2.5V to 5.5V outputs from battery inputs such as one to three NiCd/NiMH cells or one Li-Ion cell. Both devices have an internal 1A, 130mΩ N-channel MOSFET switch and a 250mΩ P-channel synchronous rectifier.
With their internal synchronous rectifier, the MAX1700/MAX1701 deliver 5% better efficiency than similar nonsynchronous converters. They also feature a pulse-frequency-modulation (PFM) standby mode to improve efficiency at light loads, and a 3µA shutdown mode.
The MAX1700/MAX1701 come in 16-pin QSOP packages (which occupy the same space as an 8-pin SO). The MAX1701 includes two comparators to generate power-good and low-battery warning outputs. It also contains a gain block that can be used to build a linear regulator using an external P-channel pass device.
For higher-power outputs, refer to the MAX1703. For dual outputs (step-up and linear regulator), refer to the MAX1705/MAX1706. For an on-board analog-to-digital converter, refer to the MAX848/MAX849.
The MAX1701 evaluation kit is available to speed design time.
