Frequently Asked Questions
What is the input voltage range of the LM20124MH?
The LM20124MH accepts an input voltage from 2.95V to 5.5V, with a nominal operating point of 5V. This range makes it compatible with single-cell Li-ion batteries and standard 3.3V or 5V power rails commonly found in embedded and portable systems.
What output current can the LM20124MH deliver?
The LM20124MH is rated for up to 4A continuous output current. It uses current-mode PWM control to maintain tight regulation and deliver fast transient response, making it suitable for powering DSPs, FPGAs, and microcontrollers with dynamic load requirements.
What package does the LM20124MH come in, and what are its dimensions?
The LM20124MH is housed in a 16-pin PowerTSSOP package (JESD-30 code R-PDSO-G16) with a body width of 4.40mm (0.173 inches). This compact footprint simplifies PCB layout and is ideal for high-density power supply designs in space-constrained applications.
Is the LM20124MH suitable as a replacement for other 4A buck regulators?
Yes. The LM20124MH can replace or be compared with other 4A synchronous buck regulators operating from a 5V input, such as the TPS62130 or LM21215A. Verify pin compatibility, switching frequency, and compensation network requirements before swapping in a design.
