描述
The MAX1729 evaluation kit (EV kit) is a low-power, step-up DC-DC converter followed by a low-dropout linear regulator. It accepts a positive input voltage between 2.7V to 5.5V and converts it to an output voltage 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 birefringence (ECB) and LCD bias-supply generation.
