This high voltage regulator integrates an N-Channel • Nearly Constant Operating Frequency With Buck Switch, and is available in thermally enhanced Line and Load Variations WSON-10 and HTSSOP-14EP packages. The • Adjustable Output Voltage constant on-time regulation scheme requires no loop • 2.5V, ±2% Feedback Reference compensation resulting in fast load transient response and simplified circuit implementation. The • Programmable Soft-Start operating frequency remains constant with line and • Thermal shutdown load variations due to the inverse relationship • LM25010Q is AEC-Q100 Grade 1 & 0 qualified between the input voltage and the on-time. The valley current limit detection is set at 1.25A. Additional TYPICAL APPLICATIONS features include: VCC under-voltage lock-out, thermal shutdown, gate drive under-voltage lock-out, and • Non-Isolated Telecommunications Regulator maximum duty cycle limiter. • Secondary Side Post Regulator • Automotive Electronics BASIC STEP-DOWN REGULATOR 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
