Make these pattern lines as thick as possible. 2) Place capacitor C1 on the input side as closely as possible to terminals no.2 and no.4 of the STR7000/7100 series. C1 may be used in combination with a smoothing capacitor for rectifying, but the above points must be taken into consideration. In cases where C1 is not provided or it is placed too far from the terminals stated above, abnormal oscillation due to poorer transient response or increased ringing may occur. 3) Connect voltage sensing terminal VO.S and GND as closely as possible to output capacitor C4 (a current of approximately 1mA flows into the VO.S terminal). If they are placed too far from C4, abnormal oscillation due to decreased regulation or increased switching ripple may occur. 4) Connect current sensing terminal C.S and GND as closely as possible to the detection resistor Rs (a current of approximately 0.5mA flows from the CS terminal). If they are placed too far from Rs, a decrease of the overcurrent setting point due to the voltage drop in the pattern, or malfunction of the protection circuit due to increased ringing may occur. sTa-PD Characteristics STR7000 Series 40 200x300x2 35 200x200x2 STR7100 Series 40 35 Power Dissipation PD (W) 30 25 20 15 10 5 Without heatsink 0 -20 0 25 50 100x200x2 Power Dissipation PD (W) Without Mica With Silicon Grease Heatsink: Aluminum Unit: mm 200x300x2 200x200x2 30 100x200x2 25 20 15 10 5 Without heatsink Without Mica With Silicon Grease Heatsink: Aluminum Unit: mm 100x100x2 75x75x2 100x100x2 75x75x2 75 100 125 0 -20 0 25 50 75 100 125 Ambient Temperature Ta (C) Ambient Temperature Ta (C) 89 qSTR7000+SI-8020 Series sTypical Characteristics (Ta=25C) STR7001+SI-8020(5V) Rise Characteristics 10 STR7002+SI-8021(12V) Rise Characteristics 20 30 STR7003+SI-8023(24V) Rise Characteristics Output Voltage VO (V) Output Voltage VO (V) 15 Output Voltage VO (V) 8 25 20 0.1 A 10 15 A 3A 6A 6A 0.1 IO= 4 IO= 3A 10 3A 5 2 5 0 0 2 4 6 8 10 12 14 16 18 20 0 0 5 10 15 20 25 30 35 40 45 0 0 5 10 15 20 6A 25 30 6 IO= 0.1 A 35 40 45 Input Voltage VIN (V) Input Voltage VIN (V) Input Voltage VIN (V) Efficiency Characteristics 100 90 80 VIN=11V Efficiency Characteristics 100 90 18V VIN= 30V Efficiency Characteristics 100 40V VIN=30V 90 50V 80 20V 80 Efficiency (%) Efficiency (%) 70 60 50 40 30 0 0 1 30V 40V 50V 70 60 50 40 0 0 Efficiency (%) 40V 70 60 50 40 0 0 2 3 4 5 6 7 Output Current IO (A) 1 2 3 4 5 6 7 1 2 3 4 5 6 7 Output Current IO (A) Output Current IO (A) STR7101+SI-8020(5V) Rise Characteristics 10 20 STR7102+SI-8021(12V) Rise Characteristics 30 STR7103+SI-8023(24V) Rise Characteristics 8 Output Voltage VO (V) Output Voltage VO (V) Output Voltage VO (V) lo= 5 10 15 20 20 6 12 A 4 A 0.1 A 10 15 lo= 6A 10 12 A 2 lO=0.1 6A 5 5 0 0 2 4 6 8 10 12 14 16 18 20 0 0 5 10 15 20 25 30 35 40 45 0 0 25 12 30 A 35 15 0.1 A 25 40 45 Input Voltage VIN (V) Input Voltage VIN (V) Input Voltage VIN (V) Efficiency Characteristics 100 90 80 Efficiency Characteristics 100 90 80 Efficiency Characteristics 100 90 VIN=30V 40V VIN=18V Efficiency (%) Efficiency (%) 70 60 50 40 30 0 0 2 4 6 8 10 VIN=1 1V 20V 30V 40V Efficiency (%) 70 60 50 40 0 0 30V 40V 50V 50V 80 70 60 50 12 14 2 4 6 8 10 12 14 0 0 2 4 6 8 10 12 14 Output Current IO (A) Output Current IO (A) Output Current IO (A) 90 |
