PRODUCTION DATA
The TPS6244x has two operating modes. Forced PWM mode is discussed in this section and PWM/PFM as discussed in Section 9.4.2.
With the MODE/SYNC pin set to high, the TPS6244x operates with pulse width modulation in continuous conduction mode (CCM). The switching frequency is either defined by a resistor from the COMP pin to GND or by an external clock signal applied to the MODE/SYNC pin. With an external clock applied to MODE/SYNC, the TPS6244x follows the frequency applied to the pin. The frequency must be in a range the device can operate at, taking the minimum on time into account.
