JAJSJ68B May 2020 – December 2023 TPS566231 , TPS566238
PRODUCTION DATA
The TPS56623x can support large duty operations by smoothly dropping down the switching frequency. When VIN / VOUT < 1.6 and the VFB is lower than internal VREF, the switching frequency is allowed to smoothly drop to make TON extended. This action is done to implement large duty operation and also improve the performance of the load transient performance. The minimum switching frequency is limited with about 165 kHz with typical 100-ns minimum off-time. The TPS56623x can support up to 98% duty cycle operation.
