Product Overview

The TPS6734ID is a Boost Converter capable of delivering 120mA from inputs as low as 3.75V. The device is pin-for-pin compatible with the MAX734 regulator and offers the following advantages: lower supply current, wider operating input-voltage range and higher output currents. The only external components required are: an inductor, a Schottky rectifier, an output filter capacitor, an input filter capacitor and a small capacitor for loop compensation. The entire converter occupies less than 0.7 in2 of PCB space when implemented with surface-mount components. An enable input is provided to shut down the converter and reduce the supply current to 3µA when 12V is not needed. It is a 170kHz current-mode PWM ( pulse-width modulation) controller with an n-channel MOSFET power switch. Gate drive for the switch is derived from the 12V output after start-up to minimize the die area needed to realize the 0.7R MOSFET and improve efficiency at input voltages below 5V.
  • Pin-for-pin compatible with MAX734
  • Programming voltage for flash memory
  • Only 5 external components required
  • 85% Typical high efficiency
  • Green product and no Sb/Br
