MAX17122, Boost-Buck Regulator

_ MAX17122 19-4951; Rev 1; 11/09 EVAALVUAAILTAIOBNLEKIT Step-Up, Step.
The MAX17122 multiple-output power-supply IC generates all the supply rails for thin-film transistor (TFT) liquidcrystal display (LCD) TV panels.

Features

* include an external-capacitor-timed, open-drain, power-good output that monitors the stepdown regulator’s feedback and a simple untimed output that monitors the positive charge-pump linear regulator’s feedback. A high-voltage stress function is available for the step-up regulator output. The GATE ou

Applications

* running directly from 12V regulated supplies. It includes a 22V internal-switch step-down regulator for digital logic, a 22V internal switch stepup regulator to power the TFT source drivers, and a temperature-compensated 36V internal-switch boostbuck regulator that produces a negative output that ca
