SLPS446D April 2014 – December 2016 CSD95379Q3M
PRODUCTION DATA.
PIN | DESCRIPTION | |
---|---|---|
NAME | NUMBER | |
SKIP# | 1 | This pin enables the Diode Emulation function. When this pin is held low, Diode Emulation Mode is enabled for the sync FET. When SKIP# is high, the CSD95379Q3M operates in Forced Continuous Conduction Mode. A tri-state voltage on SKIP# puts the driver into a very-low power state. |
VDD | 3 | Supply voltage to gate drivers and internal circuitry. |
PGND | 4 | Power ground. Needs to be connected to pin 11 on the PCB. |
VSW | 5 | Voltage switching node – pin connection to output inductor. |
VIN | 6 | Input voltage pin. Connect input capacitors to close this pin. |
BOOT_R | 7 | Bootstrap capacitor connection. Connect a minimum 0.1-µF, 16-V X5R, ceramic capacitor from BOOT to BOOT_R pins. The bootstrap capacitor provides the charge to turn on the control FET. The bootstrap diode is integrated. |
BOOT | 8 | |
PWM | 10 | Pulse-width-modulated tri-state input from external controller. Logic low sets control FET gate low and sync FET gate high. Logic high sets control FET gate high and sync FET gate low. Open or High Z sets both MOSFET gates low if greater than the tri-state shutdown hold-off time (T3HT). |
PGND | 11 | Power ground. Needs to be connected to pin 4 on the PCB. |
