Inductor L1 1) It must be suited for switching regulators. Do not use inductors as noise filters as they generate excessive heat. 2) It must have the appropriate inductance value. If the inductance is too small (150µH or lower), abnormal oscillation may occur causing operation problems in the overcurrent protection circuit within the rated current range. 3) The rated current must be satisfied. If the rated current is exceeded, magnetic saturation leads to overcurrent. 2. Capacitors C1 and C2 1) They must satisfy the withstand voltage and allowable ripple current. Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal oscillation of the IC. 2) C2 must be a low-impedance type capacitor. A low-impedance type capacitor is recommended for C2 to ensure minimum ripple voltage and stable switching operation. 3. Diode D1 The Sanken AK06 diode is recommended for D1. If you intended to use an equivalent diode, be sure to use a Schottky Barrier diode and make sure that the reverse voltage applied to terminal 2 of the IC does not exceed the value (–1V) given in the absolute maximum ratings. If you use a fast recovery diode or any other diode, application of a reverse voltage generated from the recovery or ON voltage of the diode may damage the IC. Application Variable output voltage Output voltage can be adjusted in the same way as SI-8000S in page 85. 78 qSI-8000E Series sTypical Characteristics Efficiency Characteristics(SI-8050E) 100 90 (Ta=25°C) Rise Characteristics(SI-8050E) 6 (Ta=25°C) Load Regulation(SI-8050E) 5.2 (Ta=25°C) 5 0.1A Output Voltage VO (V) Efficiency η (%) 80 70 60 50 40 0 0 N= VI 0V 1 0V 2 V 30 V 40 7V 4 0.6 A 0.3A Output Voltage VO (V) 5.1 0A IO= VIN=40V 5.0 20V 10V 7V 4.9 3 2 1 0.1 0.2 0.3 0.4 0.5 0.6 0 0 2 4 6 8 10 4.8 0 0.1 0.2 0.3 0.4 0.5 0.6 Output Current IO (A) Input Voltage VIN (V) Output Current IO (V) Overcurrent Protection Characteristics(SI-8050E) 6 (Ta=25°C) Temperature Characteristics(SI-8050E) 100 (VIN=20V, IO=0.3A) 5.3 5.2 Thermal Protection Characteristics(SI-8050E) 6 VIN=20V, IO=20mA Efficiency η (%) 5 90 Output Voltage VO (V) Output Voltage VO (V) 80 70 60 50 40 0 0 VO 5.1 5.0 4.9 4.8 4.7 0 150 4 Output Voltage VO (V) η 5 20V 4 Frequency f (kHz) VIN 40 3 =7 V 3 V f 2 2 1 1 0 0 0 0.5 1.0 1.5 2.0 Output Current IO (V) Ambient Temperature Ta (°C) 0 50 100 0 Case Temperature TC (°C) 50 100 150 200 Note on Thermal Protection: The thermal protection circuit is intended for protection against heat during instantaneous shortcircuiting.
