B048F015T14-EB: Application Field and Working PrincipleThe B048F015T14-EB evaluation board is a power-supply module designed for DC/DC and AC/DC (off-line) switch mode power supplies (SMPS). This evaluation board enables a full evaluation of the power-supply design using the power switch and compensation components.The B048F015T14-EB offers a wide range of options to meet the demands of any power-supply application, including numerous configurable features like adjustable output voltages, adjustable peak current limit, adjustable overvoltage protection (OVP), adjustable constantly current-limit (CCL), adjustable switching frequency, and more.The B048F015T14-EB also offers a number of safeguards that refer to industry safety-standards, including an integrated over-temperature protection (OTP), an external open-drain protection device, and an automatically adjustable power-save mode.The B048F015T14-EB is based on an isolated topology, meaning that its input can be from either a DC or an AC source. It utilizes a synchronous rectifying technique, which allows it to achieve high efficiency and power factor-correction (PFC). The topology also features a current-mode controller, leading to fast transient response and excellent load regulation.The controller used by the B048F015T14-EB is an integrated multiplier-based auto-zeroing amplifier with a RMS-measurement circuit. This enables a setup for an active power-factor-correction (PFC) controller for the power-supply.The evaluation board also features a wide range of both digital and analog control options. It supports digital control of AVI (adaptive voltage input), voltage level shifting, soft-start, and dynamic-clamping functions as well as an analog channel for the supply and the load.The B048F015T14-EB supports both manual and automatic modes of operation. In manual mode, an external control voltage is used to adjust the output voltage and in automatic mode, the output voltage can be adjusted using a signal from the regulator loop.The evaluation board also features a comprehensive array of protection features including over-temperature, over-current, short-circuit, over-voltage, and current-limiting detection to name a few.In conclusion, the B048F015T14-EB is an excellent choice for any power-supply application. It features a robust and reliable design that supports a wide range of features and functions while offering excellent power-supply performance.
