Frequently Asked Questions
What is the input voltage range of the LM20134MH?
The LM20134MH accepts an input voltage from 2.95 V to 5.5 V, with a nominal operating point of 5 V. This range covers standard 3.3 V and 5 V power rails used in embedded computing and industrial control boards, making it versatile for a wide variety of system power architectures.
What control topology does the LM20134MH use?
It employs current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting, superior line and load transient response, and simplified compensation network design compared to voltage-mode control schemes.
What package is the LM20134MH available in?
The LM20134MH is packaged in a 16-pin small outline IC (SOIC) package, designated JESD-30 code R-PDSO-G16. This through-hole-compatible surface-mount package provides a balance of thermal performance and compact board footprint for industrial and embedded applications.
Is the LM20134MH a synchronous or non-synchronous converter?
The LM20134MH is a synchronous buck regulator, meaning it uses an integrated low-side synchronous switch instead of an external catch diode. This reduces power dissipation and improves efficiency at moderate-to-heavy load currents compared to non-synchronous designs.
