GND 5 — Signal ground. GND (PWR) 7 — Power ground. OUTPUT 8 O Regulated output REF 2 I Feedback tap for output voltage SERIES IN1 1 — Power source for series voltage regulator. SW CURRENT CTRL 4 I/O Resistor to ground controls switching current SW IN 6 I/O Step up switching inductor node SW REG IN2 3 — Power source for step-up switching regulator. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VO Output voltage(2) –0.3 35 V VI1 Input voltage, series regulator –0.3 35 V VI2 Input voltage, switching regulator –0.3 10 V Blocking-diode reverse voltage 35 V Blocking-diode forward current 1 A SW IN Power switch current 1 A Lead temperature 1.6 mm (1/16 inch) from case for 10 seconds 260 °C TJ Junction temperature 150 °C Tstg Storage temperature –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal. 6.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±200 Electrostatic V(ESD) V discharge Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±2000 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. Pins listed as ±200-V may actually have higher performance. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
