Description for the TL1464
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.
