Working Principle

The STEVAL-ISA099V1 evaluation board is based on a switched converter type of power supply. This type of power supply relies on the high-frequency switching of solid-state components to convert an incoming AC voltage to DC voltage. It works by using a power semiconductor switch in series with two other components - a rectifier diode and an inductor. When the semiconductor switch turns on, the diode allows current to pass to the inductor. The inductor stores the energy from the current and then releases it when the switch turns off. This process is repeated at a high frequency, converting the incoming AC voltage to a lower, regulated DC voltage. The board includes protection features such as Over Voltage Protection (OVP) and Under Voltage Lockout (UVLO) to prevent damage to the circuit due to excessive current. Also included in the design is adjustable switching frequency from 50 kHz to 500 kHz, allowing users to easily adjust the switching frequency for different applications.The STEVAL-ISA099V1 evaluation board is an excellent tool for developing power supplies for various applications, allowing engineers to easily and quickly test and develop complex power supplies. The board provides engineers with an efficient, reliable and cost-effective solution for developing power supplies for their applications.
