description

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.

NOTE: When the STANDBY input is high (≥ 2.4 V), OUTPUT-2 to 4 are controlled individually. If STANDBY-2 input is low

(≤ 0.4 V), OUTPUT-2 is turned off. When CH-2 standby mode is released, CH-2 can do the soft-start function.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
