Unisonic Technologies UC3845
The UC3844 ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC3845 has UVLO thresholds of 8.4V(ON) and 7.6V(OFF) for lower voltage applications. It is normally connected to the switching power supply output through a resistor divider. The differences between UC3844 and UC3845 are the under-voltage lockout thresholds.| Part No. | UC3845 |
