The NCP1200AD100R2 from On Semiconductor is a PWM current-mode controller specifically designed for universal off-line power supplies, emphasizing low standby power. This controller features an internal structure operating at a fixed 100 kHz frequency, eliminating the need for an auxiliary winding. Its current-mode control offers excellent audio susceptibility and pulse-by-pulse control.
Key electrical specifications include a maximum supply voltage of 16V and a duty cycle of 83%. The device incorporates fault protection for current limiting, overload, and short circuits. It also features skip-cycle capability for excellent efficiency at light loads. The NCP1200AD100R2 is housed in an 8-SOIC package suitable for surface mounting.
This controller is ideal for applications such as AC-DC adapters for portable devices, offline battery chargers, and auxiliary power supplies for appliances and TVs. Its design facilitates the implementation of SMPS where standby power is a critical parameter.
