NCP630GD2T

NCP630 Linear Voltage Regulators Fast 3.0 A The NCP630 is a low dropout positive voltage regulator that is capable of providing a guaranteed output current of 3.0 A with a maximum dropout voltage of 1.25 V at 3.0 A over temperature. The fast turn on time allows step changes in loads commonly found in low voltage microprocessor applications. The NCP630 is currently offered as an adjustable output version that can be programmed down to 1.2 V with two external resistors and as a fixed output version at 3.47 V. On chip trimming adjusts the reference/output voltage to within "1.5% accuracy. Internal protection features consist of output current limiting and thermal shutdown. NCP630 is available in D2PAK package. http://onsemi.com MARKING DIAGRAM D2PAK D2T SUFFIX CASE 936A 1 NC P630xD2T AWLYWWG 5 Features • • • • • • • • Output Current of 3.0 A 1.25 V Maximum Dropout Voltage at 3.0 A Over Temperature Voltage on Shutdown Pin is TTL Compatible Reference/Output Voltage Trimmed to "1.5% Current Limit Protection Thermal Shutdown Protection −40°C to 125°C Junction Temperature Range Pb−Free Packages are Available NCP630A x A WL Y WW G Applications • • • • Microprocessor Power Supplies DSP Power Supplies SMPS Post Regulation Battery Chargers Vin INPUT Cin + 68 mF − Shutdown ADJ GND R2 + R1 Tab = Ground Pin 1.

The maximum ESR allowed for stability is 5.0 W. The capacitor should be place as close as possible to the input of the device. The placement of a ceramic capacitor in parallel is not recommend due to possible instabilities. Some situations might occur were the output pin is raised to a voltage while the input pin is at zero volts. This situation will not damage the device. If the output voltage is raised to a higher voltage than the input voltage a diode is recommended from output to input with the anode connect to the output pin. Output Capacitor Thermal Considerations A minimum output capacitor value of 33 mF is required for stability. The type of capacitor can be aluminum electrolytic or tantalum capacitor. ESR can vary up to a maximum of 2.0 ohms for stability. The capacitor should be placed as close as possible to the output of the device. The placement of a ceramic capacitor in parallel is not recommend due to possible instabilities. This series contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature is exceeded. When activated, typically at 165°C, the regulator output switches off and then back on as the die cools. As a result, if the device is continuously operated in an overheated condition, the output will appear to be oscillating. This feature provides protection from a catastrophic device failure due to accidental overheating. It is not intended to be used as a substitute for proper heatsinking. The maximum device power dissipation can be calculated by: Sense Pin The sense pin of the NCP630G will need to be connected near the output voltage. This provides great advantages when the linear regulator can’t be near the load. The sense pin will monitor the load and allow the linear regulator to adjust for losses in the line between itself and the load. Thus it will provide good accuracy for a remote load. PD + The typical application circuits for the fixed and adjustable output regulators are shown in Figures 1 and 2. The adjustable devices develop and maintain the nominal 1.216 V reference voltage between the adjust and ground pins. The adjust pin current, Iadj, is typically 40 nA and normally lower than the current flowing through R1 and R2, thus it generates a small output voltage error that can usually be ignored. For the fixed output devices R1 and R2 are included within the device. 80 JUNCTION-TO-AIR ( °C/W) 3.5 PD(max) for TA = 50°C 70 3.0 Free Air Mounted Vertically 60 ÎÎÎÎ ÎÎÎÎ ÎÎÎÎ ÎÎÎÎ 2.0 oz.

The package has an exposed metal tab that is specifically designed to reduce the junction to air thermal resistance, RqJA, by utilizing the printed circuit board copper as a heat dissipater. Figure 11 shows typical RqJA values that can be obtained from a square pattern using economical single sided 2.0 ounce copper board material. The final product thermal limits should be tested and quantified in order to insure acceptable performance and reliability. The actual RqJA can vary considerably from the graphs shown. This will be due to any changes made in the copper aspect ratio of the final layout, adjacent heat sources, and air flow.
