For testing, the soft-start circuit to the converter was set up with C SS = 0.1 µF, R SS = 100 kΩ, and R E = 1.18 kΩ. Figure 4 shows the soft-start waveform with these circuit parameters.

Soft-start initiates in the standard-buck mode and then the IC seamlessly switches to its synchronous-buck mode.The controller's output voltage can be precisely regulated to as low as 0.8 V, with a ...

Silego has brought out two more CMICs (configurable mixed-signal ICs) in its GreenPak (GPak) series of tiny, fast to programme, configurable ICs. The SLG46116V and SLG46117V are the first GPAK devices ...

A simple circuit can implement a smooth soft start for an isolated converter in a system using the LM5025 active-clamp, voltage-mode PWM controller. Figure 2 shows the concept of this secondary ...
