Description

MAXIM INTEGRATED PRODUCTS MAX1709EUI+ DC-DC Switching Boost (Step Up) Regulator, Adj., 700mV-5Vin, 3.3V-5V/4A out, 600 kHz, TSSOP-28The 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

The 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 clock synchronization capability allows for even tighter noise spectrum control. Two control inputs (ONA, ONB (complementary)) allow simple push-on, push-off control through a single momentary pushbutton switch as well as conventional on/off logic control. It features programmable soft-start and current limit for design flexibility and optimum performance with batteries. It is used in local 2.5V to 3.3V or 5V conversion, local 3.3V to 5V conversion, 3.6V or 5V RF PAs in communications handsets, routers, servers, workstations and card racks.
  • Integration reduces external component count to save space
  • On-chip 10A power MOSFET
  • 5V, 4A output from a 3.3V input
  • Fixed 3.3V or 5V output voltage or adjustable (2.5V to 5.5V)
  • Constant frequency reduces post-filtering, synchronized switching frequency (350KHz to 1000KHz)
  • Lower power consumption extends battery life
  • Quiescent power consumption is less than 1mW
  • Internal oscillator frequency of 600KHz at VOUT = VCLK = +3.6V
  • Maximum duty cycle of 94% at VOUT = VCLK = +3.6V

Good
Pretty easy to setup. The directions were easy to follow I setup in less than an hour. It’s kind of flimsy when moving it around but holds up well for sleep. Not squeaky at all.
