SLVSET0D May 2020 – October 2021 TPS61378-Q1
PRODUCTION DATA
The TPS61378-Q1 enters forced PWM mode by pulling the MODE/SYNC pin to logic high for more than five switching cycles. In forced PWM mode, the TPS61378-Q1 keeps the switching frequency constant at light load condition. When the load current decreases, the output of the internal error amplifier also decreases to keep the inductor peak current down. When the output current decreases further, the high-side switch is not turned off even if the current of the high-side switch goes negative to keep the frequency constant.
