NAME
TONB
TON
Pin Description
FUNCTION
Switching Frequency Adjustment Input for Regulator B. An external resistor
between the input power source and TONB sets the switching period (per phase)
for regulator B according to the following equation:
tSWB = (RTONB + 6.5kI) x 14.6pF
where fSWB = 1/tSWB is the nominal switching frequency.
TONB is high-impedance in shutdown. If REG B is disabled, connect TONB to GND or
VCC.
Switching Frequency Adjustment Input for Both Regulators. An external resistor
between the input power source and TON sets the switching period (per phase)
according to the following equations:
tSWA = (2 x RTON + 6.5kI) x 17.9pF
tSWB = (2 x RTON + 6.5kI) x 14.6pF
where fSW = 1/tSW is the nominal switching frequency.
If REG B is disabled:
tSWA = (RTON + 6.5kI) x 17.9pF
TON is high-impedance in shutdown.
