Product data sheet Rev. 01 — 17 March 2004 8 of 16 Philips Semiconductors TEA1622P STARplugTM 8.7.3 Efficiency An efficiency of 75 % at maximum output power can be achieved for a complete converter designed for universal mains. 8.7.4 Ripple A minimum ripple is obtained in a system designed for a maximum duty factor of 50 % under normal operating conditions, and a minimized dead time. The magnitude of the ripple in the output voltage is determined by the frequency and duty factor of the converter, the output current level, and the value and ESR of the output capacitor. 9. Limiting values [1] Pins VCC and RC are not allowed to be current driven. [2] Pins REG and AUX are not allowed to be voltage driven. [3] Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k Ω series resistor. [4] Machine model: equivalent to discharging a 200 pF capacitor through a 0.75 µH coil and a 10 Ω series resistor. Table 4: Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134).
