High-Voltage Switcher for Low Power Offline SMPS NCP1060, NCP1063 The NCP106X products integrate a fixed frequency current mode controller with a 700 V MOSFET. Available in a PDIP7, SOIC10 or SOIC16 package, the NCP106X offer a high level of integration, www.onsemi.com including softstart, frequencyjittering, shortcircuit protection, skipcycle, adjustable peak current set point, ramp compensation, and a Dynamic SelfSupply (eliminating the need for an auxiliary winding). MARKING DIAGRAMS Unlike other monolithic solutions, the NCP106X is quiet by nature: during nominal load operation, the part switches at one of the available 7 frequencies (60 kHz or 100 kHz). When the output power demand PDIP7 P106xfyyy diminishes, the IC automatically enters frequency foldback mode and CASE 626A AWL 8 provides excellent efficiency at light loads. When the power demand AP SUFFIX YYWWG reduces further, it enters into a skip mode to reduce the standby 1 1 consumption down to a no load condition. Protection features include: a timer to detect an overload or a shortcircuit event, Overvoltage Protection with autorecovery and 16 SOIC16 AC input line voltage detection (A version). NCP1063fyyyG 16 CASE 751B05 The ON proprietary integrated Over Power Protection (OPP) lets AWLYWW 1 D SUFFIX you harness the maximum delivered power without affecting your 1 standby performance simply via external resistors. For improved standby performance, the connection of an auxiliary 10 winding stops the DSS operation and helps to reduce input power SOIC10 1060fyyy consumption below 50 mW at high line. 10 CASE 751BQ ALYWX NCP106x can be seamlessly used both in nonisolated and in 1 AD or BD SUFFIX isolated topologies. 1 Features x = Power Switch Circuit Builtin 700 V MOSFET with R of 34 (NCP1060) and Onstate Resistance DS(on) (0 = 34 , 3 = 11.4 ) 11.4 (NCP1063) f = Brown In (A = Yes, B = No) Large Creepage Distance Between Highvoltage Pins yyy = Oscillator Frequency CurrentMode Fixed Frequency Operation 60 kHz or 100 kHz (060 = 60 kHz, 100 = 100 kHz) A = Assembly Location (130 kHz on demand) L, WL = Wafer Lot Adjustable Peak Current: see below table Y, YY = Year W, WW = Work Week Fixed Ramp Compensation G or = PbFree Package Direct Feedback Connection for Nonisolated Converter Internal and Adjustable Over Power Protection (OPP) Circuit SkipCycle Operation at Low Peak Currents Only ORDERING INFORMATION See detailed ordering and shipping information on page 28 of Dynamic SelfSupply: No Need for an Auxiliary Winding this data sheet.

PIN FUNCTION DESCRIPTION Pin No PDIP 7 SOIC 10 SOIC 16 Pin Name Function Pin Description 1 1 14 GND The IC Ground 2 2 5 V Powers the internal This pin is connected to an external capacitor. The V CC DD circuitry includes an autorecovery over voltage protection. 3 3 6 LIM/OPP Ipeak set / Over The current drown from the pin decreases Ipeak of the power limitation primary winding. If resistive divider from the auxiliary winding is connected to this pin it sets the OPP compen- sation level (it diminishes the peak current.) 4 4 7 FB Feedback signal This is the inverting input of the trans conductance error input amplifier. It is normally connected to the switching power supply output through a resistor divider. 5 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 optocoupler to this pin, the peak current set point is adjusted accordingly to the output power demand. 6 912 This unconnected pin ensures adequate creepage dis- tance 7,8 610 1316 Drain Drain connection The internal drain MOSFET connection www.onsemi.com 2
