9 Detailed Description

9.1 Overview

The TPS6100x Non-synchronous step-up converter typically operates at a 500-kHz frequency pulse width

modulation (PWM) at moderate to heavy load currents. The converter enters Power Save mode at low load

currents to maintain a high efficiency over a wide load. Additionally, the device integrates a circuit which removes

the ringing that typically appears on the SW-node when the converter enters the discontinuous current mode.
