1-Cell to 3-Cell / High-Power 1A / Low-Noise / Step-Up DC-DC Converters
General DescriptionThe 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, 130mΩN-
channel MOSFET switch and a 250mΩP-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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:Operating voltage. Since the regulator is bootstrapped to the output, once started it will operate down to 0.7V input.
Note 2:Start-up is tested with the circuit of Figure 2.
Note 3:In low-power mode (CLK/SEL = GND), the output voltage regulates 1% higher than low-noise mode (CLK/SEL = OUT or
synchronized).
Note 4:The regulator is in start-up mode until this voltage is reached. Do not apply full load current.
Note 5:Load regulation is measured from no-load to full load where full load is determined by the N-channel switch current limit.
Note 6:Supply current from the 3.30V output is measured between the 3.30V output and the OUT pin. This current correlates
directly to the actual battery supply current, but is reduced in value according to the step-up ratio and efficiency. Set VOUT
= 3.6V to keep the internal switch open when measuring the current into the device.
Note 7:ONA and ONBhave hysteresis of approximately 0.15xVOUT.
Note 8:Specifications to -40°C are guaranteed by design and not production tested.
