3 Description

The LM5012 non-synchronous buck converter is

designed to regulate over a wide input voltage range,

minimizing the need for external surge suppression

components. A minimum controllable on time of 50 ns

facilitates large step-down conversion ratios, enabling

the direct step-down from a 48-V nominal input to

low-voltage rails for reduced system complexity and

solution cost. The LM5012 operates during input

voltage dips as low as 6 V, at nearly 100 duty

cycle if needed, making it an excellent choice for highperformance

industrial applications.

With integrated high-side power MOSFET, the

LM5012 delivers up to 2.5 A of output current. A

constant on-time (COT) control architecture provides

nearly constant switching frequency with excellent

load and line transient response. Additional features

of the LM5012 include ultra-low IQ and a innovative

peak overcurrent protection, integrated VCC bias

supply and bootstrap diode, precision enable and

input UVLO, and thermal shutdown protection with

automatic recovery. An open-drain PGOOD indicator

provides sequencing, fault reporting, and output

voltage monitoring.

The LM5012 is available in a 8-pin SO PowerPAD?

integrated circuit package. The device 1.27-mm pin

pitch provides adequate spacing for high-voltage

applications.
