PTH03000W —3.3-V Input 6-A, 3.3-V Input Non-Isolated Wide-Output Adjust Power Module SLTS200C – MAY 2003 – REVISED DECEMBER 2003 Features NOMINAL SIZE = 0.75 in x 0.5 in (19,05 mm x 12,7 mm) • Up to 6-A Output Current • 3.3 V Input Voltage • Wide-Output Voltage Adjust (0.9 V to 2.5 V) • Efficiencies up to 95 % • 115 W/in³ Power Density • On/Off Inhibit • Under-Voltage Lockout • • • • • Output Current Limit Over-Temperature Protection Operating Temp: –40 to +85 °C Surface Mount Package Safety Agency Approvals (Pending): UL 1950, CSA 22.2 950, EN60950 & VDE Description Pin Configuration The PTH03000 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 3.3 V to provide step-down power conversion to any output voltage over the range, 0.9 V to 2.5 V. The output voltage of the PTH03000W is set within this range using a single resistor. Operating features include an on/off inhibit, output voltage adjust (trim), an output current limit, and over-temperature protection. 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.

(2) Reference the applicable package reference drawing for the dimensions and PC board layout (3) “Standard” option specifies 63/37, Sn/Pb pin solder material. 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 0.1 W 1 % resistor must be directly connected between this pin and the GND pin to set the output voltage to a value higher than 0.9 V. The temperature stability of the resistor should be 100 ppm/°C (or better). The set point range for the output voltage is from 0.9 V to 2.5 V. The resistor required for a given output voltage may be calculated from the following 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. Rset = 10 kΩ · 0.891 V Vout – 0.9 V – 4.99 kΩ The specification table gives the preferred resistor values for a number of standard output voltages.

The adjustment range is from 0.9 V to 2.5 V. The adjustment method requires the addition of a single external resistor, Rset, that must be connected directly between the Vo Adjust and GND pins 1. Table 2-1 gives the preferred value of the external resistor for a number of standard voltages, along with the actual output voltage that this resistance value provides. For other output voltages the value of the required resistor can either be calculated using the following formula, or simply selected from the range of values given in Table 2-2. Figure 2-1 shows the placement of the required resistor.

Never connect capacitors from Vo Adjust to either GND or Vout. Any capacitance added to the Vo Adjust pin will affect the stability of the regulator. V O Adj 2 Va Req’d Notes: 1. Use a 0.1 W resistor. The tolerance should be 1 %, with a temperature stability of 100 ppm/°C (or better). Place the resistor as close to the regulator as possible.

During power up, internal soft-start circuitry slows the rate that the output voltage rises, thereby limiting the amount of in-rush current that can be drawn from the input source. The soft-start circuitry introduces a short time delay (typically 10 ms) into the power-up characteristic. This is from the point that a valid input source is recognized. Figure 3-1 shows the power-up waveforms for a PTH05000W (5-V input), with the output voltage set point adjusted for a 2-V output. The waveforms were measured with a 5-A resistive load. The initial rise in input current when the input voltage first starts to rise is the charge current drawn by the input capacitors. Figure 3-1 Vin (2 V/Div) Output On/Off Inhibit For applications requiring output voltage on/off control, the PTH03000W & PTH05000W power modules incorporate an output on/off Inhibit control (pin 3). The inhibit feature can be used wherever there is a requirement for the output voltage from the regulator to be turned off. The power module functions normally when the Inhibit pin is left open-circuit, providing a regulated output whenever a valid source voltage is connected to Vin with respect to GND. Figure 3-2 shows the typical application of the inhibit function. Note the discrete transistor (Q1). The Inhibit control has its own internal pull-up to Vin potential. An open-collector or open-drain device is recommended to control this input. Turning Q1 on applies a low voltage to the Inhibit control pin and disables the output of the module. If Q1 is then turned off, the module will execute a soft-start power-up sequence. A regulated output voltage is produced within 20 msec. Figure 3-3 shows the typical rise in the output voltage, following the turn-off of Q1. The turn off of Q1 corresponds to the fall in the waveform, Q1 Vgs. The waveforms were measured with a 5-A resistive load. Vo (1 V/Div) Figure 3-2 4 VO Adj VIN =5 V 2 PTH05000W Inhibit + HORIZ SCALE: 5 ms/Div Current Limit Protection The PTHxx000W modules protect against load faults with a continuous current limit characteristic. Under a load fault condition the output current cannot exceed the current limit value. Attempting to draw current that exceeds the current limit value causes the output voltage to be progressively reduced. Current is continuously supplied to the fault until it is removed. Upon removal of the fault, the output voltage will promptly recover. Thermal Shutdown Thermal shutdown protects the module’s internal circuitry against excessively high temperatures. A rise in temperature may be the result of a drop in airflow, a high ambient temperature, or a sustained current limit condition. If the junction temperature of the internal components exceed 150 °C, the module will shutdown. This reduces the output voltage to zero. The module will start up automatically, by initiating a soft-start power up when the sensed temperature decreases 10 °C below the thermal shutdown trip point.
