The LMR36520 regulator is an easy-to-use, synchronous, step-down DC/DC
SIMPLE SWITCHER power converter. With integrated high-side and low-side power
MOSFETs, output current up to 2A is delivered over a
wide input voltage range of 4.2V to 65V. The transient tolerance that
goes up to 70V reduces the design size and cost to protect against overvoltages
and meets the surge immunity requirements of IEC 61000-4-5.
The LMR36520 uses peak-current mode control to provide excellent efficiency
and output voltage accuracy. Precision enable gives flexibility by enabling a direct
connection to the wide input voltage or precise control over device start-up and
shutdown. The power-good flag, with built-in filtering and delay, offers a true
indication of system status, eliminating the requirement for an external
supervisor.
Integration and internal compensation
eliminates many external components and provides a pinout designed for a simple PCB
layout. The feature set of the device is designed to simplify implementation for a
wide range of end equipment. The LMR36520 is
pin-to-pin compatible with the LMR36510 (65V, 1A) and LMR33610, LMR33620,
LMR33630, and LMR33640 (36V, 1A, 2A, 3A, 4A), completing the latest family of
SIMPLE SWITCHER power converters. This compatibility increases the ease of use
and scalability of wide Vin converters across various commonly used voltage and
current ratings without having the need to redesign the board layout. As a
result, the overall cost, design effort and time to market are optimized.
The LMR36520 is in an 8-pin HSOIC package.
