1 / 14 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 10 1 Publication Order Number: CS5421/D CS5421 Dual Out−of−Phase Synchronous Buck Controller with Remote Sense The CS5421 is a dual N−channel synchronous buck regulator controller. It contains all the circuitry required for two independent buck regulators and utilizes the V2™ control method to achieve the fastest possible transient response and best overall regulation, while using the least number of external components. The CS5421 features out−of−phase synchronization between the channels, reducing the input filter requirement. The CS5421 also provides undervoltage lockout, Soft Start, built in adaptive FET non−overlap and remote sense capability. The part is available in a 16 Lead SO Narrow package allowing the designer to minimize solution size. Features • V2 Control Topology • 150 ns Transient Response • Programmable Soft Start • 25 ns Gate Rise and Fall Times (with 1.0 nF load) • 40 ns Adaptive FET Nonoverlap Time • 100% Duty Cycle for Enhanced Transient Response • Internal Slope Compensation • 1.0 V 0.8% and 2.0% Error Amplifier References • 150 kHz to 750 kHz Programmable Frequency Operation • Switching Frequency Set by Single Resistor • Out−Of−Phase Synchronization Between the Channels Reduces the Input Filter Requirement • Undervoltage Lockout • On/Off Control Through Use of the COMP Pins CS5421GDR16 http://onsemi.com A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week Device Package Shipping ORDERING INFORMATION CS5421GD16 SO−16 48 Units/Rail SO−16 2500 Tape & Reel VFB1 COMP1 SGND GATE(H)1 PIN CONNECTIONS AND MARKING DIAGRAM GATE(L)1 PGND LGND VFFB1 SO−16 D SUFFIX CASE 751B 1 16 GATE(H)2 GATE(L)2 PGND2 VCC ROSC VFFB2 VFB2 COMP2 |
