† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied.  Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage4 value are with respect to network ground terminal.

The TL1464I incorporates on a single monolithic chip all the functions required in the construction of a pulse-width-modulation control circuit. Designed primarily for power supply control, the TL1464I contains an on-chip 1.5 V regulator, four error amplifiers, an oscillator, two dead-time comparators, undervoltage lockout circuitry, short circuit protection, standby control circuitry, and output circuits.

The external speed-up capacitors provide exceptional rise and fall time performance for the PNP power transistor.

The TL1464I operates from 3.1 V supply voltage and 2 pair of four-outputs (CH-1/CH-3, CH-2/CH-4 the same period) at the inverse phase of each other. As a result, the TL1464I provides high-efficiency power supply.
