LM5010SNVS307G –SEPTEMBER 2004–REVISED APRIL 2016
LM5010 High-Voltage 1-A Step-Down Switching Regulator Features Input Voltage Range:8Vto75V Valley Current LimitAt 1.25A Switching Frequency Can Exceed1 MHz Integrated N-Channel Buck Switch Integrated Start-Up Regulator No Loop Compensation Required Ultra-Fast Transient Response Operating Frequency Remains Constant With
Load and Line Variations Maximum Duty Cycle Limited During Start-Up Adjustable Output Voltage Precision 2.5-V Feedback Reference Thermal Shutdown Exposed Thermal Pad for Improved Heat
Dissipation
Applications High Efficiency Point-of-Load (POL) Regulator Non-Isolated Telecommunications Buck Regulator Secondary High Voltage Post Regulator Automotive Systems
DescriptionThe LM5010 step-down switching regulator features
all the functions neededto implementa low-cost,
efficient, buck bias regulator capableof supplyingin
excess of 1-A load current. This high-voltage
regulator contains an N-Channel Buck Switch, andis
availablein thermally enhanced 10-pin WSON and
14-pin HTSSOP packages. The hysteretic regulation
scheme requires no loop compensation, resultingin
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 detectionis set 1.25 A. Additional features include: VCC
undervoltage lockout, thermal shutdown, gate drive
undervoltage lockout, and maximum duty cycle
limiter.
