NCP1013ST130T3G PMIC - AC DC Converters, Offline Switchers by ON Semiconductor

The NCP101X series integrates a fixed--frequency current--mode controller and a 700 V MOSFET. Housed in a PDIP--7, PDIP--7 Gull Wing, or SOT--223 package, the NCP101X offers everything needed to build a rugged and low--cost power supply, including soft--start, frequency jittering, short--circuit protection, skip--cycle, a maximum peak current setpoint and a Dynamic Self--Supply (no need for an auxiliary winding).Unlike other monolithic solutions, the NCP101X is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (65 -- 100 -- 130 kHz). When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatically enters the so--called skip--cycle mode and provides excellent efficiency at light loads. Because this occurs at typically 1/4 of the maximum peak value, no acoustic noise takes place. As a result, standby power is reduced to the minimum without acoustic noise generation.
