Product details

Description

Low Frequency/Steady State Continuous Switching Method 3V FB IN + Converter for switching frequency Drive-Pulse Freq =25 kHz 4.5kƒ¶ 13.5kƒ¶ STB SET 100ƒ¶ Output R Figure 1. Block Diagram of Control Mode Switching Location The TA1319 IC is equipped with a low frequency continuous mode to lower the oscillation frequency during low load conditions to reduce loss during standby.The STB pin resistance sets the voltage used to make the transition from steady state continuous mode to low freq

Features

Equipped with low frequency PWM mode and high frequency PWM mode for effectively reducing power consumption during standby conditions. The switch to standby mode is made when the FB voltage input to pin 4 (FB IN) exceeds the set voltage. The set voltage is determined by pin 3 (STB). OPP (Over Power Protection: Lowers the OCL threshold when the input AC voltage is high. ) UVLO (Under Voltage Lock Out), OVLO (Over Voltage Lock Out) latch function equipped, OCL (Over Current Limiter) Wide AC range c.
