TPS2214
DUAL-SLOT PC CARD POWER-INTERFACE SWITCH
FOR SERIAL PCMCIA CONTROLLERS
SLVS206B – JULY 1999 – REVISED JUNE 2000
APPLICATION INFORMATION
12-V flash memory supply
The TPS6734 is a fixed 12-V output boost converter capable of delivering 120 mA from inputs as low as 2.7 V.
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. As shown in Figure 35, 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 in 2 of PCB
space when implemented with surface-mount components. An enable input is provided to shut the converter
down and reduce the supply current to 3 μ A when 12 V is not needed.
The TPS6734 is a 170-kHz current-mode PWM (pulse-width modulation) controller with an n-channel MOSFET
power switch. Gate drive for the switch is derived from the 12-V output after start-up to minimize the die area
needed to realize the 0.7- ? MOSFET and improve efficiency at input voltages below 5 V. Soft start is
accomplished with the addition of one small capacitor. A 1.22-V reference (pin 2) is brought out for external use.
For additional information, see the TPS6734 data sheet (SLVS127).
