Overview
19-1724; Rev 0; 5/00 4A, Low-Noise, High-Frequency, Step-Up DC-DC Converter General Description The MAX1709 sets a new standard of space savings for high-power, step-up DC-DC conversion.
It delivers up to 20W at a fixed (3.
3V or 5V) or adjustable (2.
5V to 5.
5V) output, using an on-chip power MOSFET from a +0.
7V to +5V supply.
Fixed-frequency PWM operation ensures that the switching noise spectrum is constrained to the 600kHz fundamental and its harmonics, allowing easy postfiltering for noise reduction.
External clock synchronization capability allows for even tighter noise spectrum control.
Quiescent power consumption is less than 1mW to extend operating time in battery-powered systems.
