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.
