External connection (1) Wiring condition is very important. Noise associated with wiring inductance may cause problems. For minimizing inductance, it is recommended to design the thick and short pattern (between large current diodos, input/output capacitors, and terminal 1,2.) Single-point grounding (as indicated) should be used for best results. (2) High switching speed and low forward voltage type schottky barrier diode should be recommended for the catch-diode D because it affects the efficiency. Please select the diode which the current rating is at least 1.2 times greater than maximum swiching current. (3) The output ripple voltage is highly influenced by ESR (Equivalent Series Resistor) of output capacitor, and can be minimized by selecting Low ESR capacitor. (4) An inductor should not be operated beyond its maximum rated current so that it may not saturate. (5) When voltage that is higher than VIN 1 , is applied to VOUT 2 , there is the case that the device is broken. Especially, in case VIN 1 is shorted to GND in normal condition, there is the case that the device is broken since the charged electric charge in output capacitor (CO) flows into input side. In such case a schottly barrier diode or a silicon diode shall be recommended to connect as the following circuit.

In the following circuit,when ON/OFF control terminal 5 becomes low by switching transistor Tr on, output voltage may be turned OFF and the device becomes stand-by mode. Dissipation current at stand-by mode becomes Max.400µA. 2. Soft start When capacitor Cs is attached, output pulse gradually expanded and output voltage will start softly. 3. ON/OFF control with soft startup For ON/OFF control with capacitor CS, be careful not to destroy a transistor Tr by discharge current from CS, adding a resistor restricting discharge current of CS. 4 L 1 IO 2 VO PQ1CG3032 5 R2 + + VIN 3 CS CIN Load RS D CO R1 Tr ON/OFF control signal ■ ON-OFF Terminal Voltage vs. Time (V) ON/OFF terminal voltage 2.3 (VTHH) 1.3 (VTHL) Duty ratio=100% 1 Duty ratio=0% 2 3 0.8 (VTHON) 0 1 2 3 Time Stand-by mode OFF-state Soft start Application Circuits NOTICE ●The circuit application examples in this publication are provided to explain representative applications of SHARP devices and are not intended to guarantee any circuit design or license any intellectual property rights.
