Table 1 accordingly gives the allowable adjustment range for each model for either series as Va (min) and Va (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor R2, between pin 12 (Vo adjust) and pins 5-8 (GND).

Refer to Figure 1 and Table 2 for both the placement and value of the required resistor; either (R1) or R2 as appropriate. The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulae. Notes: 1. Use only a single 1% resistor in either the (R1) or R2 location. Place the resistor as close to the ISR as possible. 2. 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 ISR. 4. Adjustments to the output voltage may place additional limits on the maximum and minimum input voltage for the part. The revised maximum and minimum input voltage limits must comply with the following requirements. Note that the minimum input voltage limits are also model dependant.

The function has uses in areas such as battery conservation, power-up sequencing, or any other application where the regulated output from the module is required to be switched off. The On/Off function is provided by the Inhibit control, pin 1. The ISR functions normally with pin 1 open-circuit, providing a regulated output whenever a valid source voltage is applied to Vin, (pins 2, 3, & 4). When a low-level2 ground signal is applied to pin 1 the regulator output is disabled, and the input current to the ISR is reduced to about 100µA 3/. Figure 1 shows an application schematic, which details the typical use of the inhibit function. Note the discrete transistor, Q1. The inhibit control has its own internal pull-up with a maximum open-circuit voltage of 8.3VDC. Only devices with a true opencollector or open-drain output can be used to control this pin. A discrete bipolar transistor or MOSFET is recommended. Notes: 1. The inhibit control logic is similar for all Power Trends’ modules, but the flexibility and threshold tolerances will be different. For specific information on the inhibit function of other ISR models, consult the applicable application note. 2. Use only a true open-collector device (preferably a discrete transistor) for the inhibit input. Do Not use a pull-up resistor, or drive the input directly from the output of a TTL or other logic gate. To disable the output voltage, the control pin should be pulled low to less than +1.5VDC. 3. The following equation may be used to determine the approximate current drawn from the input supply at Vin, and through Q1 when the inhibit is active. Istby = Vin ÷ 155kΩ ± 20% 4. When the inhibit control pin is active, i.e. pulled low, the maximum input voltage is limited to +30Vdc.

The Inhibit control pin is pulled high by its internal pull-up resistor. The ISR produces a fully regulated output voltage within 1-msec of either the release of the Inhibit control pin, or the application of power. The actual turn-on time will vary with the input voltage, output load, and the total amount of capacitance connected to the output Using the circuit of Figure 1, Figure 2 shows the typical rise in output voltage for the PT6101 following the turn-off of Q1 at time t =0.

Avoid capacitance greater than 500pF at the Inhibit control pin. Excessive capacitance at this pin will cause the ISR to produce a pulse on the output voltage bus at turn-on. 7. Keep the On/Off transition to less than 10µs. This prevents erratic operation of the ISR, which can cause a momentary high output voltage.
