The LMZ10504TZ-ADJ/NOPB is a SIMPLE SWITCHER® Power Module with 5.5V maximum input voltage. It is a complete, easy-to-use, DC-DC solution capable of driving up to a 4A load with exceptional power conversion efficiency, output voltage accuracy and line and load regulation. The LMZ10504 enhances thermal performance and allows for hand or machine soldering. The LMZ10504 can accept an input voltage rail between 2.95 and 5.5V and can deliver an adjustable and highly accurate output voltage as low as 0.8V. 1MHz fixed-frequency PWM switching provides a predictable EMI characteristic. Two external compensation components can be adjusted to set the fastest response time, while allowing the option to use ceramic or electrolytic output capacitors. The LMZ10504 is a reliable and robust solution with the following features lossless cycle-by-cycle peak current limit to protect for overcurrent or short-circuit fault, thermal shutdown, input undervoltage lockout and pre-biased start-up.
● Integrated shielded inductor
● Flexible start-up sequencing using external soft-start, tracking and precision enable
● Protection against in-rush currents and faults such as input UVLO and output short-circuit
● Single exposed pad and standard pinout for easy mounting and manufacturing
● Fully enable for WEBENCH™ and power designer
● Operates at high ambient temperatures
● High efficiency up to 96% reduces system heat generation
