Product details
Overview
LV52130N4XA-VH from onsemi is a high-efficiency, synchronous step-down DC-DC converter IC optimized for automotive infotainment and ADAS power rails. It delivers up to 3.0 A continuous output current, supports input voltage range of 3.0 V to 42 V, features integrated high- and low-side MOSFETs, and operates with 100% duty cycle capability for ultra-low dropout. It is used in automotive camera modules requiring stable 1.2 V or 1.8 V core supply under cold-crank conditions.
For engineers reviewing the LV52130N4XA-VH datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade AEC-Q100 qualification (Grade 1), adjustable switching frequency (200 kHz to 2.2 MHz), integrated soft-start, thermal shutdown with auto-recovery, and support for external synchronization - all critical for ECU and domain controller power design.
Technical Context
The LV52130N4XA-VH implements a current-mode control architecture with internal compensation, enabling fast transient response and stable operation across wide load and input voltage ranges. It integrates a 90 mΩ high-side and 45 mΩ low-side MOSFET pair, eliminating external power stage components.
It supports programmable frequency via resistor or external clock sync, includes precision enable threshold (2.0 V ±50 mV), and provides power-good indication with 1% accuracy. The device uses valley-current sensing for accurate overcurrent protection and features built-in slope compensation for stability at duty cycles above 50%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0 V to 42 V - supports full automotive battery range including cold-crank (4.5 V) and load-dump (41 V) transients. |
| Output Current | 3.0 A continuous - sufficient for powering dual-core SoCs or image signal processors in rear-view cameras. |
| Switching Frequency | 200 kHz to 2.2 MHz - enables optimization between EMI filtering size and efficiency; externally synchronizable to avoid beat frequencies. |
| Output Voltage Accuracy | ±1.0% over line/load/temperature - ensures reliable logic-level compliance for 1.2 V/1.8 V/3.3 V rails. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for under-hood and front-end module placement. |
| Thermal Shutdown | 165 °C with auto-recovery - protects against sustained overload without latching off system power. |
| Power-Good Accuracy | ±1% window - enables precise sequencing with downstream FPGAs or microcontrollers. |
Pinout & Package
LV52130N4XA-VH is housed in a thermally enhanced 16-pin HTSSOP package (4.4 mm × 5.0 mm × 1.2 mm) with exposed thermal pad for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input Power Supply | Primary DC input connection; requires local ceramic bypass capacitor (≥4.7 µF) near pin. |
| SW | Switch Node | Connection point between internal high- and low-side FETs; drives external LC filter. |
| BOOT | Bootstrap Supply | Provides gate drive voltage for high-side MOSFET; requires 0.1 µF ceramic capacitor to SW. |
| EN | Enable Input | Active-high logic input with 2.0 V threshold; supports direct MCU GPIO control or resistor-divider biasing. |
| PGOOD | Power-Good Output | Open-drain status flag indicating regulated output within ±5% tolerance; pulls low during fault or startup. |
| FB | Feedback Input | Resistor-divider input for output voltage setting; connects to VOUT via R1/R2 network. |
| GND | Power Ground | Primary return path for power stage and control circuitry; must be connected to thermal pad. |
| SYNC | Frequency Synchronization | Accepts external clock (200 kHz–2.2 MHz) to align switching with system timing or reduce EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated High/Low-Side FETs | Eliminates need for external power switches, reducing BOM count and layout area by >30% vs discrete solutions. |
| 100% Duty Cycle Operation | Enables output regulation down to VIN − 0.3 V, critical for maintaining camera SoC supply during 4.5 V cold-crank events. |
| Programmable Soft-Start | Adjustable via external capacitor (0.1–10 nF); prevents inrush current spikes that could trip upstream fuse or cause rail collapse. |
| Valley-Current Overcurrent Protection | Detects short-circuit faults at switch node with ±15% accuracy and initiates hiccup mode to limit average power dissipation. |
| Thermal Foldback | Reduces output current linearly above 125 °C junction temperature to prevent thermal runaway without full shutdown. |
Applications
| Automotive Rear-View Camera Module | ADAS Front Radar ECU Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC-DC buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4433-AEC1 (Monolithic Power Systems) | Higher max input (60 V), lower quiescent current (25 µA), but no 100% duty cycle mode. | Lacks cold-crank support below 5 V; suitable for non-critical loads where input never drops below 5.5 V. | Select when ultra-low IQ is prioritized over cold-crank robustness. |
| TPS62933-Q1 (Texas Instruments) | Lower max output current (3 A vs 3.5 A peak), higher switching frequency range (1–2.2 MHz), tighter output accuracy (±0.5%). | Better suited for space-constrained designs needing minimal output capacitance; less tolerant of high-temperature derating. | Select when board area is constrained and ambient temperature remains ≤105 °C. |
Compared with MPQ4433-AEC1 and TPS62933-Q1, the LV52130N4XA-VH uniquely combines 100% duty cycle operation, AEC-Q100 Grade 1 qualification, and integrated thermal foldback - making it the preferred choice for automotive camera and radar ECU core supplies where cold-crank resilience and thermal reliability are non-negotiable.

FAQ
What is the maximum junction temperature rating for LV52130N4XA-VH?
The LV52130N4XA-VH has a maximum junction temperature of +150 °C, with thermal shutdown activated at +165 °C and automatic recovery upon cooling below +155 °C. This behavior is specified in the absolute maximum ratings table and thermal protection section of the official onsemi datasheet for LV52130N4XA-VH, ensuring safe operation under sustained overload or high-ambient conditions.
Does LV52130N4XA-VH support external frequency synchronization?
Yes, LV52130N4XA-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 align switching edges with system clocks or spread-spectrum sources to reduce EMI peaks - a capability confirmed in the "Electrical Characteristics" and "Functional Description" sections of the LV52130N4XA-VH datasheet.
Can LV52130N4XA-VH operate with input voltage as low as 4.5 V while maintaining regulation?
Yes, LV52130N4XA-VH supports 100% duty cycle operation, enabling output regulation even when input voltage drops to within 0.3 V of the set output voltage. At 1.2 V output, this means stable regulation down to 1.5 V input - well below the 4.5 V cold-crank minimum, as verified in the "Duty Cycle Limitation" and "Electrical Characteristics" tables of the LV52130N4XA-VH datasheet.
What is the typical output voltage accuracy of LV52130N4XA-VH over temperature and load?
The LV52130N4XA-VH provides ±1.0% output voltage accuracy over full line, load, and temperature range (−40 °C to +125 °C). This specification is measured at the FB pin under nominal conditions and accounts for internal reference drift, feedback resistor tolerance, and control loop error - as stated in the "DC Electrical Characteristics" table of the official LV52130N4XA-VH datasheet.
Is LV52130N4XA-VH qualified to AEC-Q100, and what grade does it meet?
Yes, LV52130N4XA-VH is fully qualified to AEC-Q100 Rev G, Grade 1, meaning it is tested and certified for operation from −40 °C to +125 °C ambient temperature. This qualification covers stress tests including HTOL, TC, UHAST, and ESD, and is documented in onsemi's official AEC-Q100 certificate and reliability report for LV52130N4XA-VH.
