SNVS307G – SEPTEMBER 2004 – REVISED APRIL 2016 LM5010 High-Voltage 1-A Step-Down Switching Regulator
1 Features 3 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 1-A load current. This high-voltage
regulator contains an N-Channel Buck Switch, and is
available in thermally enhanced 10-pin WSON and
14-pin HTSSOP packages. The hysteretic regulation
scheme requires no loop compensation, resulting 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 1.25 A. Additional features include: VCC
undervoltage lockout, thermal shutdown, gate drive
undervoltage lockout, and maximum duty cycle …
