Unisonic Technologies UPSR105
UPSR105 is a high performance AC/DC power supply controller for battery charger and adapter applications. It can meet less than 10mW standby power for “Super Star” charger criteria. The UTC UPSR105 provides accurate constant voltage (CV), constant current (CC) and outstanding dynamic performance without requiring an opto-coupler.| Part No. | UPSR105 |

DESCRIPTION
The UTC SOP-8 The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies. It also eliminates the need of loop compensation circuitry while maintaining stability. The UTC UPSR105 is equipped with both cable drop compensation function to meet various cables with different lengths and gauges and adjustable line voltage compensation function. When UTC UPSR105 is used with 2nd-side synchronous rectification, better under-shoot performance and higher conversion efficiency can be achieved. The UTC UPSR105 has internal over temperature protection for itself, and also provides dedicated pin for ex ternal over temperature protection.●
