Automotive High-Voltage Switcher for Low Power Offline SMPS NCV1060, NCV1063 The NCV106X products integrate a fixed frequency current mode controller with a 670 V MOSFET. Available in a SOIC10 or www.onsemi.com SOIC16 package, the NCV106X offer a high level of integration, including softstart, frequencyjittering, shortcircuit protection, MARKING DIAGRAMS skipcycle, adjustable peak current set point, ramp compensation, and a Dynamic SelfSupply (eliminating the need for an auxiliary winding). 16 Unlike other monolithic solutions, the NCV106X is quiet by nature: SOIC16 during nominal load operation, the part switches at one of the available NCV1063fyyyG 16 CASE 751B05 AWLYWW frequencies (60 kHz or 100 kHz). When the output power demand 1 D SUFFIX diminishes, the IC automatically enters frequency foldback mode and 1 provides excellent efficiency at light loads. When the power demand reduces further, it enters into a skip mode to reduce the standby 10 consumption down to a no load condition. SOIC10 V1060fyyy 10 CASE 751BQ Protection features include: a timer to detect an overload or a ALYWX 1 AD or BD SUFFIX shortcircuit event, Overvoltage Protection with autorecovery and 1 AC input line voltage detection (A version). The ON proprietary integrated Over Power Protection (OPP) lets x = Power Switch Circuit you harness the maximum delivered power without affecting your Onstate Resistance standby performance simply via external resistors. (0 = 34 , 3 = 11.4 ) For improved standby performance, the connection of an auxiliary f = Brown In (A = Yes, B = No) winding stops the DSS operation and helps to reduce input power yyy = Oscillator Frequency (060 = 60 kHz, 100 = 100 kHz) consumption below 50 mW at high line.

If resistive divider from the auxiliary winding is connected to this pin it sets the OPP compensation level (it diminishes the peak current.) 4 7 FB Feedback Signal This is the inverting input of the trans conductance error amplifier. It Input is normally connected to the switching power supply output through a resistor divider 5 8 Comp Compensation The error amplifier output is available on this pin. The network connected between this pin and ground adjusts the regulation loop bandwidth. Also, by connecting an opto coupler to this pin, the peak current set point is adjusted accordingly to the output power demand 912 This unconnected pin ensures adequate creepage distance 610 1316 Drain Drain Connection The internal drain MOSFET connection www.onsemi.com 2
