•

3 Description

The LMR36015S regulator is an easy-to-use,

synchronous, step-down DC/DC converter. With

integrated high-side and low-side power MOSFETs,

up to 1.5 A of output current is delivered over a wide

input voltage range of 4.2 V to 60 V. Tolerance goes

up to 66 V. The transient tolerance reduces the

necessary design effort to protect against

overvoltages and meets the surge immunity

requirements of IEC 61000-4-5.

LMR36006 (60 V, 0.6 A)

LMR33620/LMR33630 (36 V, 2 A, or 3 A)

– 400-kHz, 1-MHz frequency options

Small, 2-mm × 3-mm HotRod^™package

Low power dissipation across load spectrum

– 90% efficiency at 400 kHz (24 V_IN, 5 V_OUT, 1 A)

– 93% efficiency at 400 kHz (12 V_IN, 5 V_OUT, 1 A)

– Increased light load efficiency in PFM

– Low operating quiescent current of 26 µA

Solution with few external components

Optimized for ultra low EMI requirements

– Meets CISPR25 class 5 standard

– HotRod package minimizes switch node ringing

– Parallel input path minimizes parasitic

inductance

– Spread spectrum reduces peak emissions

Create a custom design using the LMR36015S

with the WEBENCH^®Power Designer

•

The LMR36015S uses peak-current-mode control to

provide optimal efficiency and output voltage

accuracy. Load transient performance is improved

with FPWM feature in the 1-MHz regulator. 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.
