NAME
FUNCTION
Oscillator Adjustment Input. Connect a resistor (R OSC ) between OSC and GND to set the switching
frequency (per phase):
f OSC = 300kHz x 143k /R OSC
39
OSC
A 71.4k
to 432k
resistor corresponds to switching frequencies of 600kHz to 100kHz,
respectively, for SMPS1 and SMPS2. SMPS3 runs at twice the programmed switching frequency.
Switching frequency selection is limited by the minimum on-time. See the Core Switching
Frequency description in the SMPS Design Procedure section.
Slew-Rate Adjustment Pin. The total resistance R TIME from TIME to GND sets the internal slew rate:
PWM slew rate = (6.25mV/μs) x (143k /R TIME )
where R TIME is between 35.7k
and 357k .

TIME
PGND
This slew rate applies to both upward and downward VID transitions, and to the transition from boot
mode to VID mode. Downward VID transition slew rate in skip mode can appear slower because the
output transition is not forced by the SMPS.
The slew rate for startup is fixed at 1mV/μs.
Exposed Pad. Power ground connection and source connection of the internal low-side MOSFET.
