Torex’s The XC9516 is a triple output power supply mainly aimed at 11-14in TFT-LCD panels.

It can operate with input voltages between 2.5V and 5.5V.

It contains a non-synchronous step-up DC/DC converter (with integrated 1A N-channel driver transistor) whose output voltage can be set externally between 5.5V and 19V. There is a positive charge pump (doubler), with regulated output and a negative charge pump (inverter), with regulated output.

The XC9516 includes an internal voltage regulator, whose main purpose is to keep the on-resistance of the integrated driver transistor as small as possible when a low input voltage is applied.

Its switching frequency can be adjusted between 300kHz and 1.5MHz by connecting a resistance to its ROSC pin.

Protection circuits comprises thermal shutdown, UVLO (undervoltage lockout) with hysteresis, overvoltage protection (step-up DC/DC only) and short-circuit protection (one for each of the three outputs).

The device is packaged in a 4.0x4.0x0.75mm QFN-20.
