The next-generation FSB series ac regulators address and meet the power-saving requirements of the 2013 EU eco-design directive Energy-related Products (ErP) Lot 6. This standard requires the maximum power consumption of electronic devices in standby mode to be less than 0.5W. FSB series devices integrate an advanced current-mode pulse width modulator (PWM) and an avalanche-rugged 700V SenseFET in a single package. An AX-CAP method, one of the five proprietary mWSaver technologies, minimizes losses in the EMI filter stage by eliminating the X-cap discharge resistors while still meeting IEC61010-1 safety requirements. The mWSaver technology’s green-mode function provides off-time modulation, which linearly decreases the switching frequency at light-load condition to minimize switching losses. Protection features include programmable cycle-by-cycle current limiting, internal open-loop protection, built-in brown-in and brown-out protection, high and low line compensation for constant power limit, over-temperature protection with hysteresis, under-voltage lockout, and over-voltage protection. The first product released in the lineup is the FSB127H with a 2A internal MOSFET. It is available in an eight-pin dual-inline package. Price is $1.56 each/1,000.
