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.
