SPECIFICATIONS AND STANDARDS
PART NO. CE-3101 Maximum output power W 1.2 INPUT CONDITIONS Input voltage Edc V +4.5 to +5.5(5V typ.) Efficiency(typ.)∗1 % 72 OUTPUT CHARACTERISTICS Output voltage Edc V +40 Maximum output current mA 30 Output voltage setting deviation(max.) % ±4 Input variation(max.) % ±1 Load variation(max.) % ±1 Temperature variation(max.) % ±1.5 Ripple noise Ep-p(typ.)∗1, ∗2 mV 250 ∗1 Typical input voltage, maximum output current, ambient temperature 25°C. ∗2 Measuring frequency: 20MHz Output ripple noise is measured after connection of the indicated external capacitor Co to the output terminals.
OUTPUT VOLTAGE CONTROL [EXTERNAL APPLIED VOLTAGE METHOD] An external voltage is applied by the external circuit below. This controls the output voltage(Vout).
R1 External voltage C1 + – D1 R2 Vs
Vout=[0.5769–(External voltage–0.75)/R2]×68+0.75 Voltage: V Resistance: kΩ R1, C1: For removal of line noise D1: Fast recovery diode
The external voltage range should be determined by the following expression:
