The LMR36503 is the industry smallest
65 V, 0.3 A synchronous step-down DC/DC converter in 2-mm × 2-mm HotRod package.
This easy-to-use converter can handle input voltage transients up to 70 V, provide
excellent EMI performance and support fixed 5 V and other adjustable output
voltages. The transient tolerance reduces the necessary design effort to protect
against input overvoltage and meets the surge immunity requirements of IEC
61000-4-5.
The LMR36503 uses the peak current
mode control architecture with internal compensation to maintain stable operation
with minimal output capacitance. The LMR36503 with the right resistor selection from
the RT pin to ground can be externally programmed to any desired switching frequency
of operation over a wide range from 200 kHz to 2.2 MHz. The precision EN/UVLO
feature allows precise control of the device during the start-up and shutdown. The
power-good flag, with built-in glitch filter and delayed release, offers a true
indication of the system status, eliminating the requirement for an external
supervisor. The compact solution size and rich feature set of LMR36503 simplifies
implementation for a wide range of industrial applications.
