nn Expands Up to Four Phases per Chip nn Up to 80V Input or Output Voltage nn Cascade with Multiple Chips for Very High Current Applications nn Supports Up to 18 Distinct Phases from 20° to 180° nn Phases Can Share Phase Angle nn Excellent DC and Transient Current Sharing nn Phase-Lockable Fixed Frequency 125kHz to 1MHz nn Supports Bidirectional Current Flow nn RSENSE or DCR Current Sensing nn Eliminates the Need to Route Sensitive Feedback and Control Signals nn 52-Lead (7mm × 8mm) QFN Package APPLICATIONS The LT®8550 is a multiphase expander for synchronous buck DC/DC converters.
It operates in tandem with any buck DC/DC converter to increase the load current capability by adding additional phases, which are clocked outof-phase to reduce ripple current and filtering capacitance.
It easily adds phases without the need to route sensitive feedback and control signals.
