Q: What are the main features of the LMZ34202RVQR?
A: The LMZ34202RVQR is a non-isolated DC-DC power module with an integrated power solution. It supports a 4.5 V to 42 V input range, provides up to 2 A output current, and offers an adjustable output voltage from 2.5 V to 7.5 V. It includes an integrated shielded inductor and is housed in a compact 10 mm × 10 mm × 4.3 mm package. Other features include adjustable switching frequency from 200 kHz to 1 MHz, external clock synchronization, adjustable soft start, power-good output, programmable UVLO, pre-bias startup, over-current protection, and thermal shutdown.
Q: What is the LMZ34202RVQR used for?
A: The LMZ34202RVQR is used to convert a higher DC input voltage into a stable lower voltage for electronic circuits. It is suitable for industrial control systems, telecommunications equipment, distributed power supplies, embedded systems, and other applications that require a compact and efficient point-of-load power solution. Its wide input range also makes it useful in systems where the supply voltage can vary significantly.
Q: Does it have any alternative manufacturer and part number, such as?
A: Yes. Similar integrated DC-DC power modules are available from manufacturers such as Analog Devices, Monolithic Power Systems, and RECOM. Possible alternatives include Analog Devices LTM8022, Monolithic Power Systems MPM3610, and RECOM R-78E5.0-1.0. However, these devices have different electrical specifications and package configurations, so they should not be regarded as direct drop-in replacements. Input and output voltage ranges, current capability, switching frequency, efficiency, thermal performance, pin configuration, and protection functions should be carefully compared before substitution.
Q: Is technical support available for this part?
A: Yes. Technical support for the LMZ34202RVQR can include datasheet and pinout information, power-supply design guidance, external-component selection, switching-frequency configuration, thermal analysis, PCB layout recommendations, and alternative-part evaluation. Professional distributors can also assist with specification verification, sourcing, and replacement selection for prototype and mass-production applications.
