TPS92513HVDGQR Overview
A buck LED driver is a switch-mode DC-DC converter that regulates the current through an LED string rather than the voltage across it, which provides uniform brightness regardless of forward-voltage variation between LEDs. Within the broader power-management IC (PMIC) hierarchy, the TPS92513HV sits in the LED-driver category, which is itself a subset of switching regulators alongside buck, boost, and buck-boost converters optimized for light-load efficiency.
Key features include cycle-by-cycle overcurrent protection, thermal shutdown, an enable/shutdown pin, an analog adjust (ADJ) input for current programming, and a PWM dim input. The peak-current-mode control topology yields good line and load regulation and supports user-selectable switching frequencies via an external resistor. The HVSSOP-10 PowerPAD package exposes the die ground pad for low thermal resistance (about 45 C/W on a standard 2 oz. 4-layer board), which keeps junction temperatures in check at full 1.5 A output. Designers can also synchronize the device to an external clock for EMI-sensitive applications.
Typical applications include architectural and commercial LED lighting, automotive interior and exterior LED drivers, industrial signage, emergency lighting, and 24 V track-lighting fixtures. The 65-V rating gives substantial transient headroom on 24 V industrial buses where load-dump-style surges are common. The wide VIN range also supports daisy-chained LED luminaires powered from a single high-voltage rail.
When laying out the PCB, place the input ceramic bypass, the bootstrap capacitor, and the freewheeling Schottky diode as close to the IC as possible to minimize parasitic loop inductance. The exposed pad must be soldered to a copper pour spanning multiple thermal vias to keep junction temperatures within the 150 C thermal-shutdown limit during continuous 1.5 A operation.

Typical Applications
TPS92513HVDGQR is suitable for 6 applications: Industrial 24V/48V LED Lighting, Architectural Track and Downlight Fixtures, Automotive Interior and Exterior Lighting, Emergency and Safety Lighting, Horticultural and Grow-Light Fixtures, Signage and Channel-Letter Illumination.
Industrial 24V/48V LED Lighting
The TPS92513HVDGQR is well suited to industrial lighting rails fed from 24-V or 48-V bus converters because its 4.5-V to 65-V VIN tolerance covers both nominal points plus substantial transient headroom. With 1.5-A output current and integrated 200-mOhm-class MOSFET, the part drives a single high-brightness LED string while the analog ADJ pin simplifies dim-to-warm control loops. Typical efficiency reaches the mid-80 percent range at moderate step-down ratios, and thermal shutdown plus cycle-by-cycle OCP protect against field shorts in high-bay fixtures.
Recommended
Architectural Track and Downlight Fixtures
Architectural track lighting is commonly wired in series of LED modules along a single 48-V feeder, where a constant-current buck regulator eliminates brightness mismatch between modules. The TPS92513HVDGQR's 65-V rating absorbs turn-off voltage spikes from the long track inductance and its PWM-dimming input allows 0 to 100 percent brightness without audible flicker from the analog ADJ. The 10-pin HVSSOP PowerPAD footprint fits inside compact MR16- and PAR30-style housings where board area is at a premium.
Recommended
Automotive Interior and Exterior Lighting
For daytime running lights, fog lamps, and interior courtesy lighting, the TPS92513HVDGQR automotive sibling TPS92513HVQDGQRQ1 offers AEC-Q100 qualification in the same HVSSOP-10 PowerPAD. The 65-V maximum rating handles 24-V load-dump transients that exceed 40 V and the integrated short-circuit protection prevents damage during harness pin shorts. Designers typically add an EMI input filter to meet CISPR 25 conducted emissions, while the externally set switching frequency lets them place the fundamental away from AM-band receivers.
Recommended
Emergency and Safety Lighting
Battery-backed emergency luminaires sit on a charger rail that can rise above 40 V during recharge and during AC-mains brownout recovery. The TPS92513HVDGQR's 65-V headroom avoids avalanche at the input and its thermally protected PowerPAD package survives the elevated ambient temperatures inside ceiling-mounted fixtures. The PWM dimming input also supports end-of-life indicator pulses required by safety codes without adding a second driver IC.
Recommended
Horticultural and Grow-Light Fixtures
Horticultural LEDs often run from 36-V or 48-V constant-voltage buses that are pumped to 1.5-A-plus per string to achieve PPFD targets, and the TPS92513HVDGQR's 1.5-A capability combined with 65-V rating is a close fit. The wide VIN tolerance handles the elevated bus voltage seen when the upstream PFC stage's output rises at light load, and the PWM dimming input is directly compatible with 0-to-10-V dimming conversion circuits used in greenhouse controllers.
Recommended
Signage and Channel-Letter Illumination
Long-run channel-letter and edge-lit signage typically wires hundreds of LEDs in series from a 48-V supply, where any single LED failure must not open-circuit the whole string. The TPS92513HVDGQR's current-mode regulation maintains uniform brightness despite the long strings and its analog ADJ input accepts a thermistor for ambient or LED-temperature compensation. The integrated MOSFET keeps the BOM to a handful of capacitors, one inductor, and a Schottky diode, which simplifies the small form factors behind acrylic panels.

Key Differentiators
- Wide 65-V input range on the same 10-pin HVSSOP footprint (vs TPS92510DGQR)
- AEC-Q100 option in the same footprint for automotive designs (vs TPS92513HVQDGQRQ1)
- Reel-size flexibility without electrical change (vs TPS92513HVDGQT)
Design Notes
Place the input ceramic bypass capacitor (recommended 1 uF X7R minimum), the bootstrap capacitor (typical 0.1 uF X7R), and the freewheeling Schottky diode immediately adjacent to the SW, BST, and PGND pins. Keep the SW copper pour small and surrounded by PGND pour to minimize EMI loop area. The exposed thermal pad must be soldered to a continuous ground copper pour stitched with multiple thermal vias (8 to 12 vias in a 4-layer 2-oz board) - skipping this yields a thermal resistance rise that triggers shutdown at full 1.5 A.
Estimated: at full 1.5 A output from 24-V VIN to a 12-V LED string, the IC dissipates roughly (24-12) * 1.5 * (1 - efficiency fraction), where efficiency is approximately 0.85. That gives a die dissipation of approximately 2.8 W. With the package's PowerPAD and a 4-layer 2-oz board, theta_JA is around 45 C/W, yielding a junction temperature rise of about 125 C above a 70 C ambient - close to the 150 C thermal-shutdown trip. If the LED string uses a higher voltage, the dissipation falls and headroom improves. Reduce the design margin by adding a top-layer copper flood under the IC or upgrading to a 4-layer board with continuous inner copper.
Do not exceed 65 V at VIN; even brief transients above the absolute-maximum will damage the internal MOSFET and the bootstrap diode. The ADJ pin senses roughly 200 mV; using a low-precision sense resistor (>1 percent tolerance) degrades LED-current regulation. Also ensure the AGND pin is Kelvin-connected to the PowerPAD/PGND pour with a single trace or via, otherwise internal bias currents can introduce measurement offsets that drift LED brightness across load.
Compliance Information
RoHS and REACH compliant per TI product page. The standard grade is not AEC-Q100 qualified; use the TPS92513HVQDGQRQ1 variant for AEC-Q100 applications.
