MAXIM INTEGRATED PRODUCTS MAX1709EUI+ DC-DC Switching Boost (Step Up) Regulator, Adj., 700mV-5Vin, 3.3V-5V/4A out, 600 kHz, TSSOP-28 Rain & Storm Cases 3-Band EQ with EQP-1A ControlThe MAX1709EUI+ is a 4A, high frequency, step up DC to DC converter in 28 pin TSSOP package. This low noise DC to DC converter 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 +0. 7V to +5V supply. Fixed frequency PWM operation ensures that the switching noise spectrum is constrained to 600KHz fundamental and its harmonics allowing easy postfiltering for noise reduction. External
