PIN FUNCTIONS (Recommended to Use Test Points to Monitor Signal Pin Connections.) RUN1, RUN2 (F5, F9):
Run Control Pin. A voltage above
PGOOD1, PGOOD2 (G9, G8):
Output Voltage Power 1.25V will turn on each channel in the module. A voltage Good Indicator. Open drain logic output that is pulled to below 1.25V on the RUN pin will turn off the related chan- ground when the output voltage is not within ±10% of nel. Each RUN pin has a 1µA pull-up current, once the the regulation point. RUN pin reaches 1.2V an additional 4.5µA pull-up current is added to this pin.
INTVCC (H8):
Internal 5V Regulator Output. The control circuits and internal gate drivers are powered from this
DIFFOUT (F8):
Internal Remote Sense Amplifier Output. voltage. Decouple this pin to PGND with a 4.7µF low ESR Connect this pin to VOUTS1 or VOUTS2 depending on which tantalum or ceramic. INTVCC is activated when either RUN1 output is using remote sense. In parallel operation connect or RUN2 is activated. one of the VOUTS pin to DIFFOUT for remote sensing.
TEMP (J6):
Onboard General Purpose Temperature Diode
SW1, SW2 (G2, G11):
Switching node of each channel for Monitoring the VBE Junction Voltage Change with that is used for testing purposes. Also an R-C snubber Temperature. See the Applications Information section. network can be applied to reduce or eliminate switch node ringing, or otherwise leave floating. See the Applications
EXTVCC (J7):
External power input that is enabled through Information section. a switch to INTVCC whenever EXTVCC is greater than 4.7V. Do not exceed 6V on this input, and connect this pin to
PHASMD (G4):
Connect this pin to SGND, INTVCC, or float- VIN when operating VIN on 5V. An efficiency increase will ing this pin to select the phase of CLKOUT to 60 degrees, occur that is a function of the (VIN – INTVCC) multiplied by 120 degrees, and 90 degrees respectively. power MOSFET driver current. Typical current requirement
CLKOUT (G5):
Clock output with phase control using the is 30mA. VIN must be applied before EXTVCC, and EXTVCC PHASMD pin to enable multiphase operation between must be removed before VIN. devices. See the Applications Information section.
VIN (M2-M11, L2-L11, J2-J4, J9-J11, K2-K4, K9-K11):
Power Input Pins. Apply input voltage between these pins and GND pins. Recommend placing input decoupling capacitance directly between VIN pins and GND pins. 4630fa 8 For more information www.linear.com/LTM4630 Document Outline Description Typical Application Absolute Maximum Ratings Pin Configuration Electrical Characteristics Typical Performance Characteristics Pin Functions Operation Applications Information Package Description Related Parts
