Typical Applications
LV14360 is suitable for 6 applications: Industrial Power Supplies, Automotive Body Electronics, Battery-Powered Equipment, Point-of-Load Regulation, Telecom and Networking Equipment, LED Lighting Drivers.
Industrial Power Supplies
The LV14360's wide 4.3V to 60V input range and 3A output make it ideal for industrial power supplies that need to regulate from unregulated 12V or 24V buses. Its high efficiency and low quiescent current reduce power loss and heat generation, while the 2MHz switching frequency allows for compact magnetics. The device's robust thermal performance and wide temperature range ensure reliable operation in harsh factory environments.
Recommended
Automotive Body Electronics
In automotive systems, the LV14360 can step down battery voltage (typically 12V) to power ECUs, sensors, and infotainment systems. Its wide input range handles voltage transients during cranking and load dump, while the 300μA sleep-mode quiescent current minimizes battery drain when the vehicle is off. The device's AEC-Q100 qualification (if available) ensures reliability in automotive environments.
Recommended
Battery-Powered Equipment
The LV14360's low quiescent current (300μA in sleep mode) and high light-load efficiency make it suitable for battery-powered devices such as portable instruments and wireless sensors. The wide input range allows operation from multi-cell battery packs, and the shutdown current of 1μA extends shelf life. The 2MHz switching frequency enables small external components, reducing overall solution size.
Recommended
Point-of-Load Regulation
The LV14360 can be used for point-of-load regulation in distributed power architectures, converting an intermediate bus voltage (e.g., 12V or 24V) to a lower voltage for FPGAs, ASICs, or microcontrollers. Its adjustable output down to 0.8V supports low-voltage cores, and the internal compensation simplifies design. The power-good output provides a reset signal for system sequencing.
Recommended
Telecom and Networking Equipment
In telecom and networking equipment, the LV14360 can regulate from a 48V backplane to lower voltages for line cards and processors. Its 60V input rating provides headroom for transient spikes, and the high efficiency reduces cooling requirements. The 2MHz switching frequency allows for small filters, saving board space in dense designs.
Recommended
LED Lighting Drivers
The LV14360 can be configured as a constant-current LED driver by using a sense resistor in series with the LED string. Its wide input range supports various LED configurations, and the high switching frequency minimizes inductor size. The device's thermal shutdown protects against over-temperature, ensuring reliable operation in lighting fixtures.

Key Differentiators
- Wide input voltage range up to 60V (vs TPS5450DDAR)
- Low quiescent current of 300μA (vs TPS5450DDAR)
- High switching frequency of 2MHz (vs LM5164DDAR)
Design Notes
Place the input capacitor close to the VIN and GND pins to minimize input ripple and voltage spikes. Use a 10μF ceramic capacitor for the input and a 22μF ceramic capacitor for the output. The bootstrap capacitor should be placed as close as possible to the BOOT and SW pins to ensure proper high-side MOSFET driving.
The exposed pad (PAD) must be soldered to a large copper area on the PCB to dissipate heat effectively. For 3A output at high input-to-output voltage differentials, the power dissipation can be significant. Use multiple thermal vias to connect the pad to inner and bottom layers for improved thermal performance.
Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. The RT/CLK pin can be used to set the switching frequency or synchronize to an external clock; if unused, connect a resistor to GND to set the frequency. Do not exceed the absolute maximum ratings on VIN or SW pins.
