1 / 15 page © Semiconductor Components Industries, LLC, 2006 October, 2006 − Rev. 1 1 Publication Order Number: NCV8842/D NCV8842 1.5 A, 170 kHz, Buck Regulator with Synchronization Capability The NCV8842 is a 1.5 A buck regulator IC operating at a fixed−frequency of 170 kHz. The device uses the V2 t control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high−speed logic. The NCV8842 accommodates input voltages from 4.5 V to 40 V and contains synchronization circuitry. The on−chip NPN transistor is capable of providing a minimum of 1.5 A of output current, and is biased by an external “boost” capacitor to ensure saturation, thus minimizing on−chip power dissipation. Protection circuitry includes thermal shutdown, cycle−by−cycle current limiting and frequency foldback. Features • V2 Architecture Provides Ultra−Fast Transient Response, Improved Regulation and Simplified Design • 2.0% Error Amp Reference Voltage Tolerance • Switch Frequency Decrease of 4:1 in Short Circuit Conditions Reduces Short Circuit Power Dissipation • BOOST Lead Allows “Bootstrapped” Operation to Maximize Efficiency • Sync Function for Parallel Supply Operation or Noise Minimization • Shutdown Lead Provides Power−Down Option • 1.0 mA Quiescent Current During Power−Down • Thermal Shutdown • Soft−Start • Internally Fused Leads in SO−16L Package • NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes • Pb−Free Packages are Available MARKING DIAGRAMS http://onsemi.com SO−16 WB PW SUFFIX CASE 751AG 1 16 NCV8842 AWLYYWWG 1 16 18−LEAD DFN MN SUFFIX CASE 505 1 NCV8842 AWLYYWW G G 1 18 18 A = Assembly Location L, WL = Wafer Lot Y, YY = Year W, WW = Work Week E = Automotive Grade G or G = Pb−Free Package (Note: Microdot may be in either location) See detailed ordering and shipping information in the package dimensions section on page 13 of this data sheet.
