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). Figure 1 2,3,4 Vin PT6100/6200/6300 Vin Vo GND 9,10,11 Vo Vo(adj) 5,6,7,8 12 (R1) Adj Down C1 1µF Ceramic (Optional) C2 + 100µF (Req’d) R2 Adjust Up COM COM Adjust Down: Add a resistor (R1), between pin 12 (Vo adjust) and pins 9-11(Vout). Refer to Figure 1 and Table 2 for both the placement and value of the required resistor; either (R1) or R2 as appropriate. 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. 3. 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. Vin (max) = (8 x Va)V or *30/38V, whichever is less. The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulae. (R1) = Ro (Va – 1.25) Vo – Va kΩ R2 = 1.25 Ro Va – Vo kΩ Where: Vo = Original output voltage Va = Adjusted output voltage Ro = The resistance value fromTable 1 * Limit is 30V when inhibit function is active.

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 Pin 1 (Inhibit) control. 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 will be disabled. 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 open-collector or open-drain output can be used to control this pin. A discrete bipolar transistor or MOSFET is recommended. Equation 1 may be used to determine the approximate current drawn by Q1 when the inhibit is active. Equation 1 Istby = Vin ÷ 155kΩ ± 20% Figure 1 2,3,4 V in PT6100/6210/6300 Vin Vo Inh* 1 C1, 1µF (Optional) GND V out Vo(adj) 5,6,7,8 12 C2 100µF Q1 BSS138 Inh 9,10,11 + COM COM Turn-On Time: The output of the ISR is enabled automatically when external power is applied to the input. 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. The waveform was measured with a 9Vdc input voltage, and 5-Ohm resistive load. Figure 2 6 5 4 Vo (Vdc) 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. When the Inhibit control pin is active, i.e. pulled low, the maximum allowed input voltage is limited to +30Vdc. 4. Do not control the Inhibit input with an external DC voltage. This will lead to erratic operation of the ISR and may over-stress the regulator. 5. 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. 6. Keep the On/Off transition to less than 10µs. This prevents erratic operation of the ISR, which can cause a momentary high output voltage. 3 2 1 0 -0.2 For technical support and more information, see inside back cover or visit www.ti.com/powertrends 0 0.2 0.4 t (milli-secs) 0.6 0.8 1 PACKAGE OPTION ADDENDUM www.ti.com 12-Jan-2013 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Qty Drawing Eco Plan Lead/Ball Finish MSL Peak Temp Samples (3) (Requires Login) (2) PT6101A LIFEBUY SIP MODULE EBA 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6101C LIFEBUY SIP MODULE EBC 12 12 Pb-Free (RoHS) Call TI Level-1-215C-UNLIM PT6101G LIFEBUY SIP MODULE EBG 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6101H OBSOLETE SIP MODULE EBH 12 TBD Call TI Call TI PT6101J OBSOLETE SIP MODULE EBJ 12 TBD Call TI Call TI PT6101N LIFEBUY SIP MODULE EBD 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6101S OBSOLETE SIP MODULE EBF 12 TBD Call TI Call TI PT6102A LIFEBUY SIP MODULE EBA 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6102C LIFEBUY SIP MODULE EBC 12 12 Pb-Free (RoHS) Call TI Level-1-215C-UNLIM PT6102N LIFEBUY SIP MODULE EBD 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6103A LIFEBUY SIP MODULE EBA 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6103C LIFEBUY SIP MODULE EBC 12 12 Pb-Free (RoHS) Call TI Level-1-215C-UNLIM PT6103N LIFEBUY SIP MODULE EBD 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6103R LIFEBUY SIP MODULE EBE 12 12 Pb-Free (RoHS) Call TI N / A for Pkg Type PT6103S OBSOLETE SIP MODULE EBF 12 TBD Call TI Call TI (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
