PRODUCTION DATA.
Connecting the MODE input to GND enables the automatic PWM and power-save mode operation. The converter operates in PWM mode at moderate to heavy loads and in the PFM mode during light loads, which maintains high efficiency over a wide load current range.
Pulling the MODE pin high forces the converter to operate in PWM mode even at light load currents, allowing lower ripple compared to PFM mode switching. In this mode, the efficiency is lower compared to the power-save mode during light loads. For additional flexibility, it is possible to switch from power-save mode to forced PWM mode during operation. This allows efficient power management by adjusting the operation of the converter to the specific system requirements. The MODE pin must be terminated.
This pin is not available in the YBG package, where the device automatically transitions between power-save and PWM modes.
