LM73605-Q1, LM73606-Q1

SNVSB12B – NOVEMBER 2017 – REVISED MAY 2021

LM7360x-Q1 3.5-V to 36-V, 5-A or 6-A Synchronous

Step-Down Voltage Converter

1 Features

3 Description

•

AEC-Q100-qualified for automotive applications

– Device temperature grade 1: –40°C to +125°C

ambient operating temperature

– Device HBM ESD classification level 2 kV

– Device CDM ESD classification level C5

Wettable flanks QFN package (WQFN)

Low EMI and low switching noise

Low quiescent current

– 0.8 µA in shutdown (typical)

– 15 µA in active mode with no load (typical)

Wide voltage conversion range:

– t_ON-MIN= 60 ns (typical)

– t_OFF-MIN= 70 ns (typical)

The LM73605-Q1/LM73606-Q1 family of devices

are easy-to-use synchronous step-down DC/DC

converters capable of driving up to 5 A (LM73605-Q1)

or 6 A (LM73606-Q1) of load current from a supply

voltage ranging from 3.5 V to 36 V. The LM73605-

Q1/LM73606-Q1 provide exceptional efficiency and

output accuracy in a very small solution size.

Peak current-mode control is employed. Additional

features such as adjustable switching frequency,

synchronization to an external clock, power-good flag,

precision enable, adjustable soft start, and tracking

provide both flexible and easy-to-use solutions for

a wide range of applications. Automatic frequency

foldback at light load and optional external bias

improve efficiency over the entire load range. The

family requires few external components and has a

pinout designed for simple PCB layout with optimal

EMI and thermal performance. Protection features

include thermal shutdown, input undervoltage lookout,

cycle-cy-cycle current limiting, and hiccup short-

citcuit protection. The LM73605-Q1 and LM73606-Q1

devices are pin-to-pin compatible for easy current

scaling.

•

Low MOSFET ON-resistance:

– R_{DS_ON_HS}= 53 mΩ (typical)

– R_{DS_ON_LS}= 31 mΩ (typical)

•

Adjustable frequency range: 350 kHz to 2.2 MHz

Pin-selectable auto mode or forced PWM mode

Start-up into pre-biased load, fixed or adjustable

soft-start time, and tracking

Synchronizable to external clock, internal

compensation, power-good flag, and precision

enable

Cycle-by-cycle current limiting, hiccup, UVLO, and

thermal shutdown protections
