LTM4644EY#PBF Description TheLTM?4642is a complete dual4Aor single8Astep-down DC/DC μModule?(micromodule) regulator. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over input voltage ranges of 4.5V to 20V, (2.375V min with external CPWR bias), the LTM4642 supports two outputs with voltage ranges of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 4A continuous current (5A peak) for each output. LTM4644EY#PBF Features ■ Small Form Factor Dual 4A Power Supply ■ Wide Input Voltage Range: 4.5V to 20V (2.375V Min with CPWR Bias) ■ Dual 180° Out-of-Phase Outputs with 4A DC ■ Dual Outputs with 0.6V to 5.5V Range ■ Output Voltage Tracking ■ ±1.5% Maximum Total DC Output Voltage Error ■ Up to 95% Maximum Efficiency ■ Phase-Lockable Fixed Frequency 600kHz to 1.4MHz ■ Constant On-Time, Valley Current Mode Architecture ■ Selectable Burst Mode? Operation ■ Output Overvoltage and Overcurrent Protection ■ 9mm × 11.25mm × 4.92mm BGA Package LTM4644EY#PBF Applications ■ Servers ■ FPGA Power ■ Telecom and Networking Equipment |
