TI LM34923 Step Down Switching Regulator
Texas Instruments LM34923 80V, 600mA Step Down Switching Regulator features all of the functions needed to implement a low-cost, efficient buck bias regulator. TI LM34923 Step Down Switching Regulator is a high voltage device containing an 80V N-channel MOSFET switch and a startup regulator. LM34923 requires no loop compensation, resulting in fast transient response. The operating frequency remains constant with line and load variations. This TI device is ideal for use in non-isolated telecommunication buck regulators and secondary high voltage post regulators as well as +42V automotive systems.
TI LM34923 EVAL evaluation board provides the design engineer with a fully functional buck regulator, employing the constant on-time (COT) operating principle. This evaluation board provides a 5V output over an input range of 6V to 75V. The circuit delivers load currents to 500 mA, with current limit set at a nominal 1A.
