The TPS62410 includes two synchronous step-down converters. The converters operate with typically 2.25MHz
fixed frequency pulse width modulation (PWM) at moderate to heavy load currents. If Power Save Mode is
enabled, the converters automatically enter Power Save Mode at light load currents and operate in PFM (Pulse
