3 Description
The LM5012-Q1 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 ratio, enabling
the direct step-down for 48 -V nominal input to lowvoltage
rails for reduced systems complexity and
solution cost. The LM5012-Q1 operates during input
voltage dips as low as 6 V, at nearly 100 duty
cycle if needed, making it an excellent choice for highperformance
48-V battery automotive application and
MHEV/EV systems.
With an integrated high-side power MOSFET, the
LM5012-Q1 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-Q1 include ultra-low IQ operation for
high light-load efficiency, 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-Q1 2.5 A is qualified to automotive
AEC-Q100 grade 1 and 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.
