1 / 17 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 7 1 Publication Order Number: CS5422/D CS5422 Dual Out−of−Phase Synchronous Buck Controller with Current Limit The CS5422 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 CS5422 features out−of−phase synchronization between the channels, reducing the input filter requirement. The CS5422 also provides undervoltage lockout, Soft Start, built in adaptive FET non−overlap and hiccup mode overcurrent protection. The part is available in a 16 Lead SO Narrow or 24 Lead Fused SO Wide package allowing the designer to minimize solution size. Features • V2 Control Topology • Hiccup Mode Overcurrent Protection • 150 ns Transient Response • Programmable Soft Start • 100% Duty Cycle for Enhanced Transient Response • 150 kHz to 600 kHz Programmable Frequency Operation • Switching Frequency Set by Single Resistor • Out−Of−Phase Synchronization Between the Channels Reduces the Input Filter Requirement • Undervoltage Lockout • Internally Fused Leads available in 24 Lead SO Wide Package CS5422GDR16 A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week Device Package Shipping ORDERING INFORMATION CS5422GD16 SO−16 48 Units/Rail SO−16 2500 Tape & Reel VFB1 COMP1 IS+1 GATE(H)1 PIN CONNECTIONS AND MARKING DIAGRAMS GATE(L)1 GND BST IS−1 SO−16 D SUFFIX CASE 751B 1 16 GATE(H)2 GATE(L)2 VCC ROSC IS+2 IS−2 VFB2 COMP2 CS5422GDWFR24 CS5422GDWF24 SO−24L 31 Units/Rail SO−24L 1000 Tape & Reel SO−24L DWF SUFFIX CASE 751E LGND LGND LGND LGND LGND LGND LGND LGND ROSC BST VCC PGND GATE(L)2 GATE(L)1 GATE(H)2 GATE(H)1 IS+2 IS+1 IS−2 IS−1 1 24 COMP2 COMP1 VFB2 VFB1 16 24 1 1 SO−16 SO−24L http://onsemi.com |
