7 / 23 page Technical Reference Notes APC12 Centauri II MODEL: APC12 SERIES SHEET 7 OF 23 JANUARY 6, 2002 REVISION A (PRELIMINARY) Basic Operation and Features The APC08/12 Centauri family was designed specifically to address applications where on board distributed power with Point- of-Load Converters (Conversion needed as close to the IC, usually DSP’s and ASIC’s) is employed. With its wide range input and flexible programmable output, any change in the load becomes very manageable with little to no impact on time to market. All of the converters in this family are buck converters. The APC12x03 versions allow 1.8V to 6V input voltage and the APC12x08 versions allow a 5.6V to 13V input with 14V max surge. MODULE PIN ASSIGNMENT There are 4 to 7 surface mount pins on a Centauri module. The availability of pins from individual modules is relevant to its version / selected option. PIN # DESIGNATION P1 VIN Input Voltage P2 VO Output Voltage P3 GND Common Ground P4 TRIM Output Voltage Adjustment [OPTION] P5 ENABLE Output Voltage Enable P6 PGood Power Good [OPTION] P7 P Load Current Active Sharing [OPTION] INDUSTRY STANDARD PINOUT When ordered with no options, the module comes with only 4 pins – VIN, Gnd, VOUT and Enable – AND IS COMPATIBLE WITH OTHER LEADING MANUFACTURER’s FOOTPRINT. When the full-featured module is required: with Output Trim; Active Current Share and Power Good Signal PINs, “-9MA” suffix is added to the standard part number. Please refer to the Part Number Ordering Scheme for other options (including packaging). Note: When using the trim function, this module offers much more trim flexibility than the competitive footprint and also requires a jumper between the two footprints to be source compatible. Contact Factory for details. Figure 1. Pin Assignment Viewed from Top of Board. Current VIN Share Enable Trim GND VO PGood |
