General Desc ription
The MAX1700/MAX1701 are high-efficiency, low-noise,
step-up DC-DC converters intended for use in battery-
powered wireless applications. They use a synchro-
nous-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, 130m
N-
channel MOSFET switch and a 250m
P-channel
synchronous rectifier.
With their internal synchronous rectifier, the MAX1700/
MAX1701 deliver 5% better efficiency than similar non-
synchronous 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 pack-
ages (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.
