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:  
– tON-MIN = 60 ns (typical)  
– tOFF-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:  
– RDS_ON_HS = 53 mΩ (typical)  
– RDS_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
