Key Features

  • Wide 2.65 V to 6 V input range covers single Li-Ion, two-cell alkaline, and 5 V USB supply rails for portable and automotive designs
  • 600 mA output current with synchronous rectification delivers up to 95% conversion efficiency, extending battery life in low-power applications
  • Current-mode PWM control with 0.8 V adjustable output enables accurate voltage regulation from 0.8 V to 6 V in a compact 8-pin MSOP package

Applications

LTC3404MPMS8#PBF is used in portable consumer electronics, battery-powered instruments, and automotive accessory modules requiring a compact 600 mA step-down regulator powered from a 2.65 V to 6 V source. Its 0.8 V minimum output voltage and synchronous rectification make it well suited for powering low-voltage DSPs, microcontrollers, and FPGA I/O banks in space-constrained PCB designs where high efficiency across a wide load range is critical.

Frequently Asked Questions

How does LTC3404MPMS8#PBF perform at light loads to extend battery life in a portable 3.3 V to 1.8 V regulator design?

LTC3404MPMS8#PBF employs current-mode PWM control with burst mode operation at light loads, typically reducing quiescent current to below 40 µA when the 600 mA output is lightly loaded. In a 3.3 V input to 1.8 V output design, the converter maintains above 85% efficiency at load currents as low as 1 mA, significantly extending battery run-time compared to linear regulators that dissipate (3.3 V minus 1.8 V) times the load current as heat.

What output voltage range can LTC3404MPMS8#PBF regulate to when powered from a single Li-Ion cell?

With a single Li-Ion cell input ranging from 3.0 V to 4.2 V (within the 2.65 V to 6 V input spec), LTC3404MPMS8#PBF can regulate its output from 0.8 V up to approximately the input voltage minus dropout. Typical output voltages in this application are 1.8 V, 2.5 V, or 3.3 V at up to 600 mA. The 0.8 V reference allows setting any output voltage above 0.8 V using a two-resistor feedback divider.

For an automotive USB charging port supply, how does the automotive grade of LTC3404MPMS8#PBF affect its reliability?

LTC3404MPMS8#PBF is tested and specified to military-grade temperature range of -55 °C to +125 °C junction temperature, making it suitable for automotive under-hood and in-cabin environments. The automotive-grade qualification ensures the device meets stricter parametric limits over the full temperature range, supporting reliable 600 mA DC-DC conversion in vehicle USB chargers and infotainment power rails that must operate across a wide ambient temperature range from cold-start at -40 °C to summer dashboard temperatures exceeding 85 °C.
