MAX1703 1-Cell to 3-Cell / High-Power 1.5A / Low-Noise / Step-Up DC-DC Converter

The MAX1703 is a high-efficiency, low-noise, step-up DC-DC converter intended for use in battery-powered wireless applications. It uses a synchronous-rectified pulse-width-modulation (PWM) boost topology to generate a 2.5V to 5.5V output from battery inputs, such as one to three NiCd/NiMH cells or o.
