Linear Technology Corporation introduces the LTM4630-1, a dual 18A or single 36A µModule® (micromodule) regulator with high precision output voltage regulation for 28nm and sub-28nm FPGAs, ASICs and microprocessors. The core voltage of these advanced digital devices requires very accurate voltage regulation at steady state (DC) and at fast load current transients. The LTM4630-1 provides precision output voltage regulation for both conditions: (a) ±0.8% maximum total DC error over line, load and temperature (–40°C to 125°C) and (b) ±3% total error, including transients, with minimum output capacitance. To power mid to high power 28nm and sub-28nm digital devices, the LTM4630-1 can be used in parallel to current share up to 144A (i.e., 4 devices x 36A). The LTM4630-1 includes a DC/DC regulator, inductors and MOSFETs in a 16mm x 16mm x 5.01mm BGA package. The LTM4630-1 regulates an output voltage ranging from 0.6V to 1.8V and from an input voltage range of 4.5V to 15V. The user can optimize transient response of the LTM4630-1 while reducing output capacitance with an external resistor and capacitor by manipulating the loop response of the µModule regulator. With minimum output ceramic capacitors (five 220µF), the LTM4630-1’s impressive ±3% output voltage regulation window is measured with a 25% load step transient response from 12VIN, while delivering 36A to a 1.2V load. The efficiencies at 12VIN, 1.2VOUT with 20A and 36A load currents are 87.5% and 86%, respectively. Corresponding power loss values are 3.2W and 6.5W, respectively. The LTM4630-1 delivers full 36A current up to 60°C ambient, from 12VIN to 1VOUT with no air flow. Load current derates at approximately 5A per 10°C rise in ambient temperature beyond 60°C. The LTM4630-1 is offered in two VOUT DC precision grades of ±0.8% and ±1.5%. 1000-piece pricing starts at $37.15 each and $36.05 each, respectively.
