The board generates an output voltage (VOUT) of 1V for loads of 0–12A from an input voltage (PVIN) of 12V. Specifications        Input voltage (PVIN) = +12V Output voltage (VOUT) = +1V Output load (IO) = 0–12A Switching frequency (FSW) = 1.0MHz Output capacitance (CO) = 4x47µF (MLCC) Input capacitance (CIN) = 3x22µF (MLCC) Dimensions (width x length x thickness) = 61mm x 89mm x 1.6mm Connections Name PVIN PGnd VOUT PGnd VIN VCC PGnd En PGood SCL SDA SALERT SYNC Load Output voltage selector Output transient ripple voltage Identifier J1 J4 J3 J2 VIN VCC PGnd TP11 PGood J5 J5 SALERT J6 J7 J8 J9 Description Input voltage (+12V) Ground for input voltage Output voltage (+1V) Ground for output voltage LDO input voltage Internal supply (VCC) – output of an LDO regulator Power ground Enable Power Good I2C/PMBUS clock line I2C/PMBUS data line SMBALERT# External sync signal Used to connect load: 20-pin Intel Mini Slammer connector Used to select output voltage before power up Used for measurement: 50Ω ultra-miniature coaxial connector The board is configured for a single input supply. An internal low drop-out regulator generates the internal supply (VCC) from VIN. The Enable (En) input is connected to PVIN through a resistor divider, so that no external Enable signal is needed. Operation To use the evaluation board: 1. Connect a well-regulated +12V input supply to PVIN (J1) and Gnd (J4). 2. Connect a load of 0–12A to VOUT (J3) and Gnd (J2).
