Description

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.
