3 / 10 page For technical support and more information, see inside back cover or visit www.ti.com Note A: Characteristic data has been developed from actual products tested at 25°C. This data is considered typical data for the ISR. Efficiency vs Output Current Power Dissipation vs Output Current Performance Data; Vin =5.0 V (See Note A) Output Ripple vs Output Current PT6460 Series 14-A 5-V Input Adjustable Integrated Switching Regulator Pin Descriptions VIN: The positive supply voltage input for the module with respect to the common GND. VOUT: This is the regulated output voltage from the mod- ule with respect to the common GND. GND: The common node to which the input, output, and external control signals are referenced. Inhibit*: This is an open-collector (open-drain) negative logic input that is referenced to GND. Pulling this pin low disables the module’s output voltage. If Inhibit* is left open-circuit, the output will be active whenever a valid input source is applied. Typical Characteristics Vo Adjust: This pin is used to trim the output voltage over a typical range of ±15 % of nominal. The adjust- ment method uses an external resistor. The resistor is connected from Vo Adjust to either the GND or (+)Sense, in order to adjust the output either up or down, respec- tively. Consult the related application note for the adjust limits on a specific part. Vsense: An external remote sense input is provided to allow the regulation circuit to compensate for voltage drop between the module and the load. For optimal voltage accuracy Vsense should be connected to VOUT. If desired, Vsense may also be left open circuit. 50 60 70 80 90 100 0246 8 10 12 14 Iout (A) PT6461 PT6462 PT6463 PT6464 PT6465 PT6466 PT6467 0 10 20 30 40 50 0246 8 10 12 14 Iout (A) PT6462 PT6463 PT6464 PT6461 PT6465 PT6466 PT6467 0 1 2 3 4 5 02468 10 12 14 Iout (A) SLTS178B - JANUARY 2003 - REVISED JUNE 2003 |
