Product details
Overview
LV52130N0XA-VH from onsemi is a high-efficiency synchronous buck DC-DC converter IC designed for automotive body electronics, delivering up to 3.0 A continuous output current with input voltage range of 4.5 V to 42 V and adjustable output voltage from 0.8 V to 5.5 V. It integrates high- and low-side MOSFETs, supports programmable soft-start, and operates over –40 °C to +125 °C ambient temperature.
For engineers reviewing the LV52130N0XA-VH datasheet, pinout, applications, or equivalent options, key selection considerations include automotive-grade AEC-Q100 qualification, integrated power stage, adjustable switching frequency (200 kHz to 2.2 MHz), current-mode control architecture, and built-in protection features including thermal shutdown and overcurrent limiting.
Technical Context
The LV52130N0XA-VH implements a current-mode controlled synchronous buck topology with internal high-side and low-side N-channel MOSFETs. It features adaptive non-overlap timing to prevent shoot-through and supports external synchronization via SYNC pin across 200 kHz–2.2 MHz.
Control loop stability is ensured by internal compensation optimized for ceramic output capacitors, and the device includes dedicated EN pin with adjustable undervoltage lockout (UVLO) threshold and hysteresis for robust system-level power sequencing in automotive environments.

FAQ
What is the AEC-Q100 qualification status of LV52130N0XA-VH?
The LV52130N0XA-VH is fully qualified to AEC-Q100 Grade 1 standards, meaning it has passed stress testing for operation from –40 °C to +125 °C ambient temperature and meets automotive reliability requirements for body electronics applications. This qualification covers HTOL, TC, UHAST, and ESD testing per the AEC-Q100 specification, and the LV52130N0XA-VH part number appears explicitly in onsemi's official AEC-Q100 certified product list.
Does LV52130N0XA-VH require external MOSFETs?
No, the LV52130N0XA-VH integrates both high-side and low-side N-channel MOSFETs within the IC, eliminating the need for external power switches. This integration reduces board space, simplifies layout, and improves efficiency by optimizing gate drive timing and minimizing parasitic inductance. The LV52130N0XA-VH delivers up to 3.0 A continuous output current using only an external inductor and output capacitor.
Can LV52130N0XA-VH synchronize to an external clock?
Yes, the LV52130N0XA-VH supports external frequency synchronization via its SYNC pin, accepting TTL/CMOS-compatible clock signals from 200 kHz to 2.2 MHz. This feature allows designers to eliminate beat frequencies in multi-converter systems, align switching with noise-sensitive components, or meet strict EMI emission limits-without modifying the LV52130N0XA-VH's internal oscillator or compensation network.
What protection features are built into LV52130N0XA-VH?
The LV52130N0XA-VH includes cycle-by-cycle overcurrent protection, thermal shutdown, input undervoltage lockout (UVLO) with hysteresis, and output overvoltage protection. All protections trigger automatic recovery upon fault clearance, and no external components are needed to enable them. These safeguards ensure robust operation in harsh automotive environments where voltage transients and thermal overload are common failure modes for the LV52130N0XA-VH.
Is there a recommended PCB layout guideline for LV52130N0XA-VH?
Yes, onsemi provides a detailed layout guide for the LV52130N0XA-VH in its official datasheet (document number NVL52130-D), emphasizing short, wide power loops for VIN–SW–VOUT, placement of the thermal pad directly beneath the IC with ≥6 thermal vias to inner ground planes, and separation of analog (FB, TS, EN) traces from noisy switching nodes. Adhering to these guidelines ensures optimal thermal performance, EMI suppression, and regulation accuracy for the LV52130N0XA-VH.
