PIN FUNCTIONS (Recommended to Use Test Points to Monitor Signal Pin Connections.) RUN1, RUN2 (F5, F9):
Run Control Pin. A voltage above
INTVCC (H8):
Internal 5V Regulator Output. The control 1.25V will turn on each channel in the module. A voltage circuits and internal gate drivers are powered from this below 1.25V on the RUN pin will turn off the related chan- voltage. Decouple this pin to PGND with a 4.7µF low ESR nel. Each RUN pin has a 1µA pull-up current, once the tantalum or ceramic. INTVCC is activated when either RUN1 RUN pin reaches 1.2V an additional 4.5µA pull-up current or RUN2 is activated. is added to this pin.
TEMP (J6):
Onboard General Purpose Temperature Diode
DIFFOUT (F8):
Internal Remote Sense Amplifier Output. for Monitoring the VBE Junction Voltage Change with Connect this pin to VOUTS1 or VOUTS2 depending on which Temperature. See the Applications Information section. output is using remote sense. In parallel operation con- nect one of the V
EXTVCC (J7):
External power input that is enabled through OUTS pin to DIFFOUT for remote sensing. a switch to INTVCC whenever EXTVCC is greater than 4.7V.
SW1, SW2 (G2, G11):
Switching node of each channel Do not exceed 6V on this input, and connect this pin to that is used for testing purposes. Also an R-C snubber VIN when operating VIN on 5V. An efficiency increase will network can be applied to reduce or eliminate switch node occur that is a function of the (VIN – INTVCC) multiplied by ringing, or otherwise leave floating. See the Applications power MOSFET driver current. Typical current requirement Information section. is 30mA. VIN must be applied before EXTVCC, and EXTVCC

CLKOUT (G5):
Clock output with phase control using the and GND pins. Recommend placing input decoupling PHASMD pin to enable multiphase operation between capacitance directly between VIN pins and GND pins. devices. See the Applications Information section.
