... ICs. Its high level of integration allows the design of a cost effective power supply with a very low number of external components. The TEA1532 can also be used in fixed frequency, Continuous Conduction Mode (CCM) converter designs for low voltage, high current applications. At low power (standby) levels, the system operates in cycle skipping mode which minimizes the switching losses during standby ...
