MAX1709 Datasheet - Maxim

MAX1709 4A / Low-Noise / High-Frequency / Step-Up DC-DC Converter

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 spect.

MAX1709 Features

* programmable soft-start and current limit for design flexibility and optimum performance with batteries. The maximum RMS switch current rating is 10A. For a device with a lower current rating, smaller size, and lower cost, refer to the MAX1708 data sheet. o On-Chip 10A Power MOSFET o 5V, 4A Output f
