DC2367A - LTM4632 Demo Board | Ultrathin Triple Output Buck μModule Regulator for DDR-QDR4 Memory, 3.6V ≤ VIN ≤ 15V, ±3A VDDQ/VTT, 10mA VREF

Demonstration circuit DC2367A features the LTM®4632EV μModule® regulator, a tiny low-profile high-performance high efficiency dual step-down regulator for DDR power. LTM4632 has an operating input voltage range of 3.6V to 15V. The output voltage of channel 1 (VDDQ) is resistor programmable from 0.6V to 2.5V and is capable of delivering up to 3A of output current. The output voltage of channel 2 (VTT) is set to regulate ½ of the voltage on the VDDQIN pin which can provided by either the channel 1 output or an external reference voltage. It can source or sink up to 3A of output current. A 10mA buffered output of VDDQIN/2 is also provided for supplying VREF voltage for DDR memory. DC2367A also provides the option for paralleling channels 1 and 2 together for up to 6A capable VTT rail.
