The LTM4633’s three switchers have separate input power pins and operate from input voltages between 4.7V to 16V. With the addition of an external bias supply above 4.5V, the minimum operating input voltage decreases to 2.375V. The three switchers, operating from the same internal or optional external clock signal, are internally phase shifted by 120° to minimize input ripple. For loads in excess of 10A, channels 1 and 2 can be paralleled to support up to 20A. Output overvoltage and overcurrent fault protections are included in the regulator. The LTM4633’s internal temperature can be observed via two internal temperature diode monitors located next to the power stages.
The LTM4633 is available with guaranteed performance over the -40°C to +125°C or -55°C to +125°C internal temperature range. The µModule regulator is available for immediate delivery from stock, priced starting at $35.95 each for 1,000 piece quantities. For more information, visit www.linear.com/product/LTM4633.
