Part Details:

LM2695 January 2006 High LM2695High Voltage (30V, 1.25A) Step Down Switching Voltage RegulatorGeneral Description n Ultra-Fast transient response n Operating frequency remains constant with load current The LM2695 Step Down Switching Regulator features all of and input voltage (30V the functions needed to implement a low cost, efficient, buck n Maximum Duty Cycle Limited During Start-Up bias regulator capable of supplying 1.25A to the load. Thisbuck regulator contains a 33V N-Channel Buck Switch, and n Adjustable output voltage , is available in the thermally enhanced LLP-10 and TSSOP- n Valley Current Limit At 1.25A 1.25A) 14EP packages. The hysteretic regulation scheme requires n Precision internal reference no loop compensation, results in fast load transient re- n Low bias current sponse, and simplifies circuit implementation. The operating n Highly efficient operation frequency remains constant with line and load variations due n Thermal shutdown to the inverse relationship between the input voltage and the Step on-time. The current limit detection is set at 1.25A. Additional Typical Applications features include: VCC under-voltage lockout, thermal shut-down, gate drive under-voltage lockout, and maximum duty n High Efficiency Point-Of-Load (POL) Regulator cycle limiter. n Non-Isolated Telecommunication Buck Regulator Down n Secondary High Voltage Post Regulator Features Package n Integrated 33V, N-Channel buck switch n Integrated start-up regulator n LLP-10 (4 mm x 4 mm) Switching n Input Voltage Range: 8V to 30V n TSSOP-14EP n No loop compensation required n Exposed Thermal Pad For Improved Heat Dissipation Basic Step Down Regulator Regulator 20170431 © 2006 National Semiconductor Corporation DS201704 Connection Diagrams
