Thermal shutdown
When the controller junction temperature reaches 150 ± 10 °C, the device shutdown.
Both MOSFET are turned OFF and the soft-start capacitor is discharged.
The device does not restart until the junction temperature goes down to 120 °C and until the
voltage on the soft-start capacitor reaches 0.5 V.
Signal ground and power ground
SGND (L8) and PGND (bank 2) are connected together on the module.
Connect to SGND the capacitor for PGDLY and SS_INL, the resistor for FB and OS.
Connect to PGND the return for SS_INL.
It is important to not create a ground loop between SGND, PGND and other GND present on
the application circuit (see
Figure 9.
Input capacitors
The input capacitor present on the module is not able to sustain the input RMS current.
Connect 2 x 2.2 μF 16 V X7R ceramic capacitor (Cin) closed to the input pins VIN and
PGND (bank 1 and bank 2), to satisfy minimum functional requirement.
Connect proper low impedance capacitors to reduce the input ripple current, according to
the application requirement.
Output capacitors
The output capacitors present on the module are able to sustain output RMS current.
Connect 2 x 330 μF POSCAP SANYO capacitor (Co) or equivalent, closed to the output pins
VOUT and PGND (bank 3 and bank 2), to guarantee output voltage stability and specified
voltage ripple.
