MAX1729 Datasheet (Maxim) - ECB and LCD Display Bias Supply with Accurate Output Voltage and Temperature Compensation

MAX1729, ECB and LCD Display Bias Supply with Accurate Output Voltage and Temperature Compensation

The MAX1729 micropower step-up/step-down DC-DC converter is ideally suited for electrically controlled birefringence (ECB) and liquid-crystal-display (LCD) biassupply generation.

It provides step-up/step-down voltage conversion and reduces output ripple by using a step-up DC-DC converter followed by

MAX1729 Features

* low quiescent current (67µA typical). A logic-controlled shutdown mode further reduces quiescent current to 0.4µA typical. The MAX1729 features an input that dynamically adjusts the output voltage to control display color or contrast. It offers two feedback modes: internal and external. Internal fee
