The LTM4723 is a complete dual 5A output switching mode step‐down μModule® (micromodule) DC-to-DC power supply in a tiny 4.25mm × 4.25mm × 1.15mm land grid array (LGA) package. The package includes the switching controller, MOSFETs, inductors, and all supporting components. Operating over an input voltage range of 2.25V to 5.5V, the LTM4723 supports two outputs with a programmable output voltage range of 0.5V to 3.6V set by external resistors. The two outputs can be paralleled for a single 10A load. Only a few ceramic input and output capacitors are needed. The LTM4723 operates in forced continuous mode (FCM) for low-noise, pulse‐skipping mode (PSM), or Burst Mode operation for high efficiency at light loads. The LTM4723 supports output voltage tracking for supply-rail sequencing. LTM4723 high switching frequency and current-mode architecture enable a fast transient response to line-and-load changes without sacrificing stability. Other features include precision run thresholds, PGOOD signals, output overvoltage protection, thermal shutdown, and output short‐circuit protection. The LTM4723 is a lead (Pb) free and RoHS-compliant device.
