n
±0.8% Maximum Total DC Output Error Over Line
The LTM®4650-1A/LTM4650-1B is dual 25A or single 50A
and Load (LTM4650-1A)
output step-down µModule® (power module) regulator n
±3% Transient Output Error with Minimum
with ±0.8% (LTM4650-1A) and ±1.5% (LTM4650-1B)
Output Capacitance
total DC output error with ±3% transient output error. n Dual 25A or Single 50A Output Included in the package are the switching controller, n 4.5V to 15V Input, 0.6V to 1.8V Output Voltage Range power FETs, inductors, and all supporting components. n Differential Remote Sense Amplifier External compensation allows for fast transient response n Current Mode Control/Fast Transient Response to minimize output capacitance when powering FPGAs, n Current Sharing Up to 300A ASICs, and processors. With synchronized multiphase n 16mm × 16mm × 5.01mm BGA Package parallel current sharing, six LTM4650-1 devices can de- liver up to 300A. The LTM4650-1 is offered in a 16mm × 16mm × 5.01 BGA package, with SnPb (BGA) or RoHS
