Product Description

The LMR14050SSQDDAQ1 is a SIMPLE SWITCHER 40V, 5A step down converter with 40µA IQ in 8 pin HSOP package. With a wide input range from 4V to 40V it is suitable for various applications from industrial to automotive for power conditioning from unregulated sources. The regulator"s quiescent current is 40µA in sleep mode which is suitable for battery powered systems. An ultra low 1µA current in shutdown mode can further prolong battery life. A wide adjustable switching frequency range allows either efficiency or external component size to be optimized. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes external components of the device. It has built-in protection features such as cycle by cycle current limit, thermal sensing and shutdown due to excessive power dissipation and output overvoltage protection. It is used in telecom and datacom systems, general purpose wide Vin regulation and industrial power supplies.
Automotive grade AEC-Q100 qualified
Operating temperature range from -40°C to 125°C
HBM ESD classification level H1C, CDM ESD classification level C4A
90mohm high side MOSFET, minimum switch-on time is 75ns & current mode control
Adjustable switching frequency from 200KHz to 2.5MHz, frequency synchronization to external clock
Spread spectrum option for reduced EMI, internal compensation for ease of use
High duty cycle operation supported, precision enable input, 1µA shutdown current
External soft start, thermal, overvoltage and short protection
ESD sensitive device, take proper precaution while handling the device.
