Description
The PTH12000 series of non-isolated power modules are small in size and high on performance. Using double-sided surface mount construction and synchronous rectification technology, these regulators deliver up to 6 A of output current while occupying a PCB area of about half the size of a standard postage stamp. They are an ideal choice for applications where space, performance and cost are important design constraints. The series operates from an input voltage of 12 V to provide step-down power conversion to a wide range of output voltages. W-suffix devices are adjustable from 1.2 V to 5.5 V, and L-suffix devices are adjustable from 0.8 V to 1.8 V. The output voltage is set within the adjustment range using a single external resistor. Operating features include an on/off inhibit, output voltage adjust (trim), and the ability to start up into an existing output voltage or prebias. A non-latching o v e r- c u r r e n t trip provides protection against load faults. Target applications include telecom, industrial, and general purpose circuits, including low-power dual-voltage systems that use a DSP, microprocessor, or ASIC. Package options include both throughhole and surface mount configurations.

Pin Descriptions
Vin: The positive input voltage power node to the module, which is referenced to common GND. Vout: The regulated positive power output with respect to the GND node. GND: This is the common ground connection for the `Vin' and `Vout' power connections. It is also the 0 VDC reference for the `Inhibit' and `Vo Adjust' control inputs. Inhibit: The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a lowlevel ground signal to this input disables the module's output and turns off the output voltage. When the Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left opencircuit, the module will produce an output whenever a valid input source is applied. Vo Adjust: A 1-% resistor must be connected between this pin and GND (pin 1) to set the output voltage of the module higher than its lowest value. The temperature stability of the resistor should be 100 ppm/°C (or better). The set-point range is 1.2 V to 5.5 V for W-suffix devices, and 0.8 V to 1.8 V for L-suffix devices. The resistor value required for a given output voltage may be calculated using a formula. If left open circuit, the output voltage will default to its lowest value. For further information on output voltage adjustment consult the related application note. The specification tables also give the preferred resistor values for a number of standard output voltages.

Notes: (1) See SOA curves or consult factory for appropriate derating. (2) The set-point voltage tolerance is affected by the tolerance and stability ofR SET . The stated limit is unconditionally met if RSET has a tolerance of 1% with 100 ppm/°C or better temperature stability. (3) The pk-pk output ripple voltage is measured with an external 10 µF ceramic capacitor. See the standard application schematic. (4) The Inhibit control (pin 3) has an internal pull-up to Vin, and if left open-circuit the module will operate when input power is applied. A small lowleakage (<100 nA) MOSFET is recommended to control this input. See application notes for more information. (5) The regulator requires a minimum of 100 µF input capacitor with a minimum 750 mArms ripple current rating. For further information, consult the related application note on Capacitor Recommendations. (6) An external output capacitor is not required for basic operation. Adding 100 µF of distributed capacitance at the load will improve the transient response. (7) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance. (8) This is the typical ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 m as the minimum when using max-ESR values to calculate.
