4 / 8 page ![]() Absolute Maximum Ratings (Note1) Symbol Parameter Rating Unit VIN VIN Supply Voltage(VIN to Gnd) ‐0.3 ~ 45 V VSW SW to GND Voltage Pulse Width > 20ns ‐1 ~ 45 V Pulse Width < 20ns ‐3 ~ 45 V EN, FB to GND Voltage ‐0.3 ~ 6 V VBS BS to GND Voltage VSW ‐ 0.3 ~ VSW +6 V VBS‐SW BS to SW Voltage ‐0.3 ~ 6 V PD Power Dissipation Internally Limited W TJ Junction Temperature 150 ºC TSTG Storage Temperature ‐65 ~ 150 ºC TSDR Maximum Lead Soldering Temperature (10 Seconds) 260 ºC Note1: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Thermal Characteristics Symbol Parameter Typical Value Unit θJA Junction‐to‐Ambient Resistance in free air (Note 2) SOT‐23‐6 250 °C/W Note 2: θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. Recommended Operation Conditions (Note3) Symbol Parameter Range Unit VIN VIN Supply Voltage 4.5 ~ 40 V VOUT Converter Output Voltage 0.8V ~ 75%VIN V IOUT Converter Output Current Continue 0 ~ 300 mA < 10ms 0 ~ 600 mA VOUT/VIN Maximum Ratio(Note 4) HM8115 75 % VOUT/VIN Minimum Ratio(Note 5) HM8115 12 % TA Ambient Temperature ‐40 ~ 85 oC TJ Junction Temperature ‐40 ~ 125 oC 40V, 600MA, 1MHz synchronous Buck Converter HM8115 |
