♦ High-Accuracy Reference Voltage (±1%)

♦ On-Chip Temperature-Sensor Output

♦ 2.7V to 5.5V Input Range

The MAX1729 evaluation kit (EV kit) is a low-power,

step-up DC-DC converter followed by a low-dropout lin-

e a r re g ula tor. It a c c e p ts a p os itive inp ut volta g e

between 2.7V to 5.5V and converts it to an output volt-

age ranging from 2.5V to 16V. The output voltage is

dynamically adjustable through an external 3kHz to

12kHz pulse-width-modulated (PWM) control signal. An

on-chip temperature sensor provides compensation for

display temperature characteristics. This makes the

MAX1729 ideally suited for electrically controlled bire-

fringence (ECB) and LCD bias-supply generation

♦ Dynamic Control of Output Voltage

♦ 0.4µA Typical Shutdown Current

♦ 10-Pin µMAX Package

♦ Surface-Mount Construction

♦ Fully Assembled and Tested

The MAX1729 EV kit is a fully assembled and tested

surface-mount board. Follow the steps below to verify

board operation. Do not turn on the power supply

until all connections are completed.

1000pF ceramic capacitor

3-pin jumper

JU1

1) Connect a 2.7V to 5.5V supply to the pads marked

VIN and GND.

2) Connect a voltmeter and load, if any, to the VOUT

pad.

3) Place the shunt on JU1 across pins 2 and 3.

4) Turn on the power and verify that the output voltage

is approximately 16.35V.

5) For othe r outp ut volta g e s , re fe r to the Outp ut

Voltage Control section.

Jumper JU1, in the 2-3 position, connects CTLIN to

VIN. This places the output voltage at maximum and is

equivalent to applying a PWM signal with a 100% duty

cycle.

In the 1-2 position, CTLIN is connected to GND. This

places the MAX1729 into shutdown mode and is equiv-

alent to applying a PWM signal with a 0% duty cycle.

When applying a PWM signal to the CTLIN pad, the

shunt must be removed from jumper JU1.
