Saturation control as a function of the load current prevents any oversaturation of the output power device preventing excessive substrate current (quiescent current). http://onsemi.com 3 CONFIDENTIAL AND PROPRIETARY NOT FOR PUBLIC RELEASE NCV4276 Setting the Output Voltage (Adjustable Version) The output voltage range of the adjustable version can be set between 2.5 V and 20 V (Figure 4). This is accomplished with an external resistor divider feeding back the voltage to the IC back to the error amplifier by the voltage adjust pin VA. The internal reference voltage is set to a temperature stable reference voltage of 2.5 V. The output voltage is calculated from the following formula. Ignoring the bias current into the VA pin, VIN VOUT Iq Figure 3. Single Output Regulator with Key Performance Parameters Labeled Q [(R1 R2) Vref ]R2 Heat Sinks A heat sink effectively increases the surface area of the package to improve the flow of heat away from the IC and into the surrounding air. Each material in the heat flow path between the IC and the outside environment will have a thermal resistance. Like series electrical resistances, these resistances are summed to determine the value of RΘJA: RJA RJC RCS RSA (3) where RΘJC is the junction-to-case thermal resistance, RΘCS is the case-to-heatsink thermal resistance, RΘSA is the heatsink-to-ambient thermal resistance. Calculating Power Dissipation in a Single Output Linear Regulator The maximum power dissipation for a single output regulator (Figure 3) is: RΘJC appears in the package section of the data sheet. Like RΘJA, it too is a function of package type. RΘCS and RΘSA are functions of the package type, heatsink and the interface between them. These values appear in heat sink data sheets of heat sink manufacturers. (1) VIN(max)Iq where VIN(max) is the maximum input voltage, VOUT(min) is the minimum output voltage, IOUT(max) is the maximum output current for the application, IQ is the quiescent current the regulator consumes at IOUT(max). Once the value of PD(max) is known, the maximum permissible value of RΘJA can be calculated: T RJA 150°C A PD SMART REGULATOR } Control Features Use R2 < 50 k to avoid significant output voltage errors due to VA bias current. Connecting VA directly to Q without R1 and R2 creates an output voltage of 2.5 V. Designers should consider the tolerance of R1 and R2 during the design phase. The input voltage range for operation (pin I) of the adjustable version is between (Q + 0.5 V) and 40 V. Internal bias requirements dictate a minimum input voltage of 4.3 V. The dropout voltage for output voltages less than 4 V is (4.3 V - Q). PD(max) [VIN(max) VOUT(min)] IOUT(max) IOUT IIN (2) The value of RΘJA can then be compared with those in the package section of the data sheet. Those packages with RΘJA’s less than the calculated value in Equation 2 will keep the die temperature below 150°C. In some cases, none of the packages will be sufficient to dissipate the heat generated by the IC, and an external heatsink will be required. http://onsemi.com 4 CONFIDENTIAL AND PROPRIETARY NOT FOR PUBLIC RELEASE NCV4276 VOUT Q Vref = 2.5 V Current Limit and Saturation Sense CQ 22 µF R1 + VA R2 Figure 4.
