The LMZ31704RVQR is a non-isolated step-down power module from Texas Instruments, integrating an inductor and power MOSFETs in a compact 42-B3QFN package. It delivers up to 4A of continuous output current with an input voltage range of 2.95V to 17V. The output voltage is adjustable from 0.6V to 5.5V with 1% reference accuracy.
This module uses current mode control and supports adjustable switching frequency from 200kHz to 1200kHz, with synchronization capability to an external clock. Efficiency reaches up to 95% with light-load efficiency mode for improved performance at low currents. Protection features include overcurrent protection (OCP), overtemperature protection (OTP), and programmable undervoltage lockout (UVLO).
The LMZ31704RVQR is designed for point-of-load applications requiring high density and reliability. It supports current sharing for parallel operation to achieve higher output current. Additional features include power good output, remote sense, output voltage sequencing/tracking, and adjustable slow start.
The module is surface mountable in a 10mm x 10mm x 4.3mm B3QFN package, suitable for automated assembly. It operates over a temperature range of -40°C to 85°C.
