LM5010
High Voltage 1A Step Down Switching Regulator
General Description
The LM5010 Step Down Switching Regulator features all the
functions needed to implement a low cost, efficient, buck
bias regulator capable of supplying in excess of 1A load
current. This high voltage regulator contains an N-Channel
Buck Switch, and is available in thermally enhanced LLP-10
and TSSOP-14EP packages. The hysteretic regulation
scheme requires no loop compensation, 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 valley current limit detection is
set at 1.25A. Additional features include: V
CC
under-voltage
lockout, thermal shutdown, gate drive under-voltage lockout,
and maximum duty cycle limiter.
