TA1307P

TA1307P 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).
