Typical Characteristics Graphs a) Operating Window b) Efficiency vs. Load b) Current Setting The output current can be adjusted using Rset resistor: • Disconnect Rset resistor to set full load at 2.1 A / 35 V condition • Connect Rset resistor to set output current (see below table and curve); for Rset = 3.9 kOhm, the output is full load at 1.42 A / 52 V condition • The unit has minimum output current at … 1A when the Rset is less than 1kOhm • The output voltage is limited by maximum output power (if the output current is set at 2.1 A, the maximum output voltage will be 35 V; if the output current is set at 1.42 A, the maximum output voltage will be 52 V) Output vs. Rset Curve 3. Protection a) Output Short Circuit Protection The unit is protected when output is short thus avoiding fire hazard, shock hazard and damage to the unit. After the short circuit fault condition is removed, the unit will be in auto recovery mode. b) Output Over Voltage Protection When no load condition occurs, the unit will clamp output voltage to the OVP Voltage avoiding damage to the unit. After the load is connected, the unit will be in auto recovery mode. When load open condition occurs, the unit will be latch on. The OVP Voltage varies according to the Rset resistor value (see below curve and table) and under 56 V. c) Over Temperature Protection The unit is protected when IC is over temperature thus avoiding fire hazard and shock hazard. cooled down, the unit will be in auto recovery mode. After the temperature is Output Current by Dimming Legal and additional information. About Samsung Electronics Co., Ltd.
