High-Speed Response Non -Isolated POL DC -DC Converter BSV-H Series BDD20150227 Bellnix DC-DC Converter 6. Temperature derating The product requires placement on PCB with good airflow due to a design to release heat through the PCB. The lines to the converter should be taken thick and wide, especially lines to the GND pin, for it has a large heat release. The derating curve below is when mounted onto the double -sided board of copper coating thickness 35µm, copper coating dimension 100mm x 100mm (both sides) and PCB thickness 1.6mm. Please use it as a reference because the heat release characteristics may change depending on wiring. Since the temperature characteristics are largely affected by PCB and the ambient temperature, it is important to make sure that the IC (refer to the outer dimensions) surface temperature of the converter does not exceed 120ºC when operated at the max ambient temperature in an actual device. -30 -20-40 0 10-10 30 4020 50 70 8060 90 出力電流[A] 周囲温度[℃] ：風速0.0[m/s]出力電圧3.3[V] 入力電圧5.0[V] ■通電条件 ：風速1.0[m/s] ：風速2.0[m/s] Power conditions Input voltage 5.0[V] Output voltage 3.3[V] Output current [A] Ambient temperature [ºC] Wind velocity Wind velocity Wind velocity

Usage information 8-1 Standard connection diagram Vin 1 4 Load 5,8 SW R1: Vout Down設定抵抗 C1 : 47μF C2 : 22μF +Vin P-Good On/Off GND -Sense Trim +Sense +Vout BSV-3.3S16R0H Open=On Short=Off Note 1: The product requires that it be mounted on the PCB since more than 70% of the heat is released through GND pins (5, 8pin) and the rest through +Vin pin and +Vout pin. The patterns should be taken wide enough to release heat when designing. Note 2: Keep ON/OFF pin open when not using ON/OFF control. Note 3: Keep Trim pin open when not using adjustable output. Note 4: GND pins (5, 8pin) are connected internally. These two pins should be connected to GND line to make the best use of the product. Note 5: Make sure that Sense pin is connected on the board. No connection of Sense pin may result in the voltage output being higher than rated voltage. Note 6: Avoid wiring patterns directly underneath this product (the first layer). This shall not apply to any area other than the surface layer on the converter side. Recommended capacitor C1 = 47μF C2 = 2.2μF to 200μF typ. 10000μF max. C1: Not required as long as impedance is very low and lines between +Vin side and the converter are connected thick and short. For high impedance, adding a capacitor of low ESR such as an organic semiconductor solid capacitor or a multi-layered ceramic capacitor is recommended. C2: Not required due to an internal output capacitor. A multi -layered ceramic capacitor placed on the load side will be recommended to satisfy electrical characteristics (to reduce ripple noise).

High-Speed Response Non -Isolated POL DC -DC Converter BSV-H Series BDD20150227 Bellnix DC-DC Converter 8-4 Adjustable method for output voltage Keep Trim pin (7pin) OPEN, when using output voltage at 3.3V without adjustment. Output voltage may be adjusted between 0.8 and 3.3V by connecting a resistor between Trim pin (7pin) and -Sense pin (6pin). Connect -Sense pin to GND (5pin). Wiring for Trim pin should be short and straight preferably when using adjustable output voltage feature. If noise appears on the pin, it causes mal-function. The below formula should be referred for external resistance. It is important to check output voltage and adjust resistance in an actual device.
