Note: The PT6320 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications. Pkg Style 200 PT6320 2,3,4 5,6,7,8 9,10,11 12 V IN GND GND V OUT C2 + 1 V OADJ INH Q1 C1 • Low Voltage Input (7V) • 90% Efficiency • Adjustable Output Voltage • Internal Short Circuit Protection • Over-Temperature Protection • On/Off Control (Ground Off) The PT6320 series is a low volt- age input (typically 7V) version of Power Trends’ high-performance 3A, 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 90% typical efficiency with open-collector on/ off control and adjustable output voltage. Quiescent current in the shutdown mode is less than 100µA. PT6320 SLTS065 (Revised 6/4/98) |
