LM2695 Datasheet | National Semiconductor

Description The LM2695 Step Down Switching Regulator features all of the functions needed to implement a low cost, efficient, buck bias regulator capable of supplying 1.25A to the load. This buck regulator contains a 33V N-Channel Buck Switch, and is available in the thermally enhanced LLP-10 and TSSOP14EP packages. The hysteretic regulation scheme requires no loop pensation, results in fast load transient response, and simplifies circuit implementation. The operating .. frequency remains constant with line and load variations due to the inverse relationship between the input voltage and the on-time. The current limit detection is set at 1.25A. Additional features include: VCC under-voltage lockout, thermal shutdown, gate drive under-voltage lockout, and maximum duty cycle limiter. n Ultra-Fast transient response n Operating frequency remains constant with load current and input voltage n Maximum Duty Cycle Limited During Start-Up n Adjustable output voltage n Valley Current Limit At 1.25A n Precision internal reference n Low bias current n Highly efficient operation n Thermal shutdown Typical Applications n High Efficiency Point-Of-Load (POL) Regulator n Non-Isolated Telemunication Buck Regulator n Secondary High Voltage Post Regulator Features n n n n Integrated 33V, N-Channel buck switch Integrated start-up regulator Input Voltage Range: 8V to 30V No loop pensation required Package n LLP-10 (4 mm x 4 mm) n TSSOP-14EP n Exposed Thermal Pad For Improved Heat Dissipation Basic Step Down Regulator © 2006 National Semiconductor Corporation DS201704 .national.
