TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA1307P
Integrated Circuit For Standby Power-Supply Control
TA1307P is a switching power-supply IC used as a standby
power-supply control such as small power-supply.
This IC, Slight power-supply can do that a MOSFET is
controlled in intermittent, and this IC is optimum IC as objects
for power-supply control, such as color TV, monitor, VCR, DVD,
FAX, printer, etc.
Main Characteristics
· Burst mode PWM pulse output
· The over current protection circuits to power MOSFET for a
drive are built in.
· UVLO (Under Voltage Lock Out), OVLO (Over Voltage Lock
Out) with Latch, OVLO on/off function
OCL (Over Current Limmiter),
Select SW for IC active/IC not active are built in.
· The starting current until UVLO is canceled about 100 µA.
· Wide range input voltage: (85 V to 264 V).
