NAME

FUNCTION
This low-voltage logic input indicates power usage and sets the operating mode together
with DPRSLPVR as shown in the truth table below. While DPRSLPVR is low, if PSI is forced low, the
controller is immediately set to (N-1)-phase forced-PWM mode. The controller returns to N-phase
forced-PWM mode when PSI is forced high.
The controller is in N-phase skip mode during startup including boot mode, but is in N-phase forced-
PWM mode during the transition from boot mode to VID mode, during soft-shutdown, irrespective of
the DPRSLPVR and PSI logic levels. However, if phases 2 and 3 are disabled by connecting CSP2,
CSP3 to VCC, then only phase 1 is active in the above modes.

Switching Frequency Setting Input. An external resistor between the input power source and this pin
sets the switching frequency according to the following equation:
f SW = 1/(C TON x (R TON + 6.5k Ω ))

TON
CLKEN
PWRGD
DRSKP
where C TON = 16.26pF.
The external resistor must also satisfy the requirement [V IN(MIN) /R TON ] ≥ 10μA where V IN(MIN) is the
minimum V IN value expected in the application.
TON is high impedance in shutdown.
Clock Enable Open-Drain Logic Output Powered by V 3P3 . This inverted logic output indicates when the
output voltage sensed at FB is in regulation. CLKEN is forced high in shutdown and during soft-start and
soft-stop transitions. CLKEN is forced low during dynamic VID transitions and for an additional 20μs after
the transition is completed. CLKEN is the inverse of PWRGD, except for the 5ms PWRGD startup delay
period after CLKEN is pulled low. See the startup timing diagram (Figure 9). The CLKEN upper threshold
is blanked during any downward output-voltage transition that happens when the controller is in skip
mode, and stays blanked until the slew-rate-controlled internal-transition-related PWRGD blanking period
is complete and the output reaches regulation.
Open-Drain Power-Good Output. After output-voltage transitions, except during power-up and power-
down, if FB is in regulation, then PWRGD is high impedance.
PWRGD is low during startup, continues to be low while the output is at the boot voltage, and stays
low until 5ms (typ) after CLKEN goes low, after which it starts monitoring the FB voltage and goes
high if FB is within the PWRGD threshold window.
PWRGD is forced low during soft-shutdown and while in shutdown. PWRGD is forced high impedance
whenever the slew-rate controller is active (output-voltage transitions), and continues to be forced
high impedance for an additional 20μs after the transition is completed.
The PWRGD upper threshold is blanked during any downward output-voltage transition that happens
when the controller is in skip mode, and stays blanked until the slew-rate-controlled internal-transition-
related PWRGD blanking period is complete and the output reaches regulation.
A pullup resistor on PWRGD causes additional finite shutdown current.
Driver Skip Control Output. Push/pull logic output that controls the operating mode of the skip-mode
driver IC. DRSKP swings from V DD to GND. When DRSKP is high, the driver ICs operate in forced-
PWM mode. When DRSKP is low, the driver ICs enable their zero-crossing comparators and operate
in pulse-skipping mode. DRSKP goes low at the end of the soft-shutdown sequence, instructing the
external drivers to shut down.
