Linear single output 50A or dual output 25A μModule regulator

Linear Technology Corporation launches a dual output 25A or a single output 50A buck type micro-module (μModule®) regulator LTM4650, the device built-in shielded inductor, MOSFET and two DC / DC regulations The device IC is all placed in a small heat resistance reinforced plastic package. The device is encapsulated by a 16mm BGA of 16 mm x 16mm x 5.01 mm BGA, which has been built into a patented radiator. The radiator is connected to the MOSFET and inductor, which can quickly scatter heat from the internal to the top of the package, while the surface of the heat sink is exposed to the air. The heat dissipation performance can be further improved by air flow or air flow plus an external heat sink. When there is no external heat sink, the LTM4650 can provide 50A current from 12vin to 0.9vout at 12 Vin to 0.9 VOUT at ambient temperature of 71 ° C and 200LFM airflow or ambient temperatures up to 77 ° C and 400LFM. The precise current mode architecture of the LTM4650 allows 4 devices to achieve multi-phase flow, allowing up to 300A current to ASIC, FPGA, and microcontrollers. The DC / DC conversion efficiency can be improved by using Linear / DC regulator IC of Linear, a powerful gate driver and low loss MOSFET. When 50A current is supplied, the efficiency of 5 Vin and 1.8 VOUT is 92%, while 12vin, 1.0 VOUT is 86%. By using a differential distal detection amplifier compensates for voltage difference due to circuit board trace impedance, the LTM4650 can ensure that the maximum overall DC output voltage accuracy is ± 1.5% in the range of voltage, load and temperature variation. The LTM4650 has a rated operating temperature range from -40oC to 125oC. Thousands of batches were $ 46.75 per piece.
