8 / 30 page 8 FN6398.3 June 14, 2010 PGOOD - Power good open-drain output. Connect externally with 680 Ω to VCCP or 1.9kΩ to 3.3V. PSI# - Current indicator input. When asserted low, indicates a reduced load-current condition and initiates single-phase operation. PMON - Analog output. PMON is proportional to the product of Vsen and droop voltage. RBIAS - 147k Ω resistor to VSS sets internal current reference. VR_TT# - Thermal overload output indicator with open-drain output. Over-temperature pull-down resistance is 10 Ω. NTC - Thermistor input to VRTT# circuit and a 60µA current source is connected internally to this pin. SOFT - A capacitor from this pin to GND sets the maximum slew rate of the output voltage. SOFT is the non-inverting input of the error amplifier. OCSET - Overcurrent set input. A resistor from this pin to VO sets DROOP voltage limit for OC trip. A 10µA current source is connected internally to this pin. VW - A resistor from this pin to COMP programs the switching frequency (for example, 6.45k Ω ≅ 400kHz). COMP - This pin is the output of the error amplifier. FB - This pin is the inverting input of error amplifier. FB2 - There is a switch between FB2 pin and the FB pin. The switch is closed in single-phase operation and is opened in two phase operation. The components connecting to FB2 are to adjust the compensation in single phase operation to achieve optimum performance. VDIFF - This pin is the output of the differential amplifier. VSEN - Remote core voltage sense input. RTN - Remote core voltage sense return. DROOP - Output of the droop amplifier. The voltage level on this pin is the sum of VO and the droop voltage. DFB - Inverting input to droop amplifier. VO - An input to the IC that reports the local output voltage. VSUM - This pin is connected to the summation junction of channel current sensing. VIN - Battery supply voltage. It is used for input voltage feed forward to improve input line transient performance. VSS - Signal ground. Connect to local controller ground. VDD - 5V control power supply. ISEN2 - Individual current sharing sensing for Channel 2. ISEN1 - Individual current sharing sensing for Channel 1. N/C - Not connected. Grounding this pin to signal ground in the practical layout. BOOT2 - This pin is the upper gate driver supply voltage for Phase 2. An internal boot strap diode is connected to the PVCC pin. UGATE2 - Upper MOSFET gate signal for Phase 2. PHASE2 - The phase node of Phase 2. Connect this pin to the source of the Channel 2 upper MOSFET. PGND2 - The return path of the lower gate driver for Phase 2. LGATE2 - Lower-side MOSFET gate signal for Phase 2. PVCC - 5V power supply for gate drivers. LGATE1 - Lower-side MOSFET gate signal for Phase 1. PGND1 - The return path of the lower gate driver for Phase 1. PHASE1 - The phase node of phase 1. Connect this pin to the source of the Channel 1 upper MOSFET. UGATE1 - Upper MOSFET gate signal for Phase 1. BOOT1 - This pin is the upper-gate-driver supply voltage for Phase 1. An internal boot strap diode is connected to the PVCC pin. VID0, VID1, VID2, VID3, VID4, VID5, VID6 - VID input with VID0 is the least significant bit (LSB) and VID6 is the most significant bit (MSB). VR_ON - Digital enable input. A logic high signal on this pin enables the regulator. DPRSLPVR - Deeper sleep enable signal. A logic high signal on this pin indicates the micro-processor is in deeper-sleep mode and also indicates a slow C4 entry or exit rate with 41µA discharging or charging the SOFT capacitor. DPRSTP# - Deeper sleep slow wake up signal. A logic low signal on this pin indicates the micro-processor is in deeper-sleep mode. CLK_EN# - Digital output for system clock. Goes active 10µs after VCORE is within 10% of Boot voltage. 3V3 - 3.3V supply voltage for CLK_EN#. ISL6266, ISL6266A |
