  • Low Voltage Input (7V)
  • 89% Efficiency
  • Adjustable Output Voltage
  • Internal Short Circuit Protection
  • Over-Temperature Protection
  • On/Off Control (Ground Off) The PT6120 series is a low volt- age input (typically 7V) version of Power Trends’ high-performance 1A, 12 pin SIP Integrated Switching Regulators (ISRs). These ISRs are de- signed with premium low threshold FETs for those applications requiring very low input/output voltage differentials such as battery powered equipment. This high- performance ISR family offers a unique combination of features combining 89% typical efficiency with open-collector on/ off control and adjustable output voltage. Quiescent current in the shutdown mode is less than 100µA.

T able 1 accordingly gives the allowable adjustment range for each model for either series as V a (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). Adjust Down: Add a resistor (R1), between pin 12 (Vo adjust) and pins 9-11(Vout). Refer to Figure 1 and T able 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 loca- tion. Place the resistor as close to the ISR as possible. 2. Never connect capacitors from V o 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 depen- dant. V in (max) = (8 x V a)V or *30/38V , whichever is less. *Limit is 30V when inhibit function is active. PT6x0x/PT6x1x series: Vin (min) = (V a + 4)V or 9V , whichever is greater. PT6x2x series: Vo <10V; V in (min) = (V a + 2.0)V or 7.0V , whichever is greater. Vo ≥10V; V in (min) = (V a + 2.5)V Figure 1 The values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulae. Ro (Va – 1.25)(R1) = Vo – Va kΩ
