NCP1010: High Voltage Switching Regulator for Offline SMPS
For complete documentation, see the data sheet
Product Description
The NCP101X series integrates a fixed-frequency current-mode controller and a 700 V voltage MOSFET. Housed in a PDIP7
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.
