7.3.1 Pulse Width Modulation (PWM) Operation
If the MODE pin is LOW and at load currents larger than half the inductor ripple current, the device operates in pulse width modulation in continuous conduction mode (CCM) as shown in Figure 7-1. The PWM operation is based on an adaptive constant on-time control with stabilized switching frequency. To achieve a stable switching frequency in a steady state condition, the on-time is calculated as:
Equation 1.
If the MODE pin is HIGH, the converter maintains a forced-PWM operation for all load currents.
