This IC is a compound power supply developed for LCD panels and combines a booster + inversion 4-channel switching power supply with a LDO2 channel.
Both the booster and inversion have a built-in switching element to reduce the mounting footprint.
In addition, external component adjustment can be used to set the output voltage, oscillation frequency, soft start time, and protective circuit dead zone time.
It also has such built-in protective functions as overcurrent protection, over voltage protection, and thermal shutdown.

1. Input voltage range	2.7 to 5.5V
2. Output voltage setting range	Booster: 6.5 to 16V Inversion: -19 to -6V
3. Built-in switching element
4. Oscillation frequency	100 to 500kHz
5. Overcurrent protective circuit
6. Over voltage protective circuit
7. Built-in thermal shutdown
