3 Description

The LMZM23601 integrated-inductor power module is

specifically designed for space-constrained industrial

applications. The device is available in two fixed

output voltage options of 5 V and 3.3 V, and an

adjustable (ADJ) output voltage option supporting

a 1.2-V to 15-V range. The LMZM23601 has an

input voltage range of 4 V to 36 V and can

deliver up to 1000-mA of output current. This power

module is extremely easy to use, requiring only

two external components for a 5-V or 3.3-V output

design. All aspects of the LMZM23601 are optimized

for performance driven and low EMI industrial

applications with space-constrained needs. An open-

drain, Power-Good output provides a true indication

of the system status and negates the requirement

for an additional supervisory component, saving cost

and board space. Seamless transition between PWM

and PFM modes along with a no-load supply current

of only 28 µA ensures high efficiency and superior

transient response for the entire load-current range.

For easy output current scaling the LMZM23601 is

pin-to-pin compatible with the 500-mA output current

capable LMZM23600.
