Product details
Overview
TPS92513HVDGQR from Texas Instruments is a 1.5 A buck LED driver IC with integrated 220-mΩ high-side MOSFET, 4.5–60 V input range, ±5% LED current accuracy, and 100 kHz–2 MHz adjustable switching frequency. It delivers stable constant-current drive for multi-LED strings in street lighting and industrial illumination systems.
For engineers reviewing the TPS92513HVDGQR datasheet, TPS92513HVDGQR pinout, TPS92513HVDGQR application, or TPS92513HVDGQR equivalent, key selection criteria include analog/PWM dual dimming support, RT/CLK synchronization capability, UVLO hysteresis programmability, and HVSSOP PowerPAD™ thermal performance under continuous conduction mode.
Technical Context
The TPS92513HVDGQR implements peak-current mode control with fixed-frequency operation, enabling precise line/load regulation and simplified compensation. Its internal oscillator supports resistor-programmed (RT) or external clock-synchronized (CLK) modes, with PLL lock-in time ≤100 µs and minimum pulse width of 140 ns.
It integrates analog current adjustment via IADJ (0–1.8 V → ISENSE = VIADJ/6), dedicated PWM dimming with 100 Hz–1 kHz range, cycle-by-cycle overcurrent protection (6 A typical), and thermal shutdown at 165°C with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 60 V - supports wide-range DC supplies including 48 V industrial rails and 56 V PoE++ lighting systems. |
| Max Output Current | 1.5 A - delivers full-rated current into LED strings up to 23 V output (7× white LEDs) with <±5% accuracy. |
| Switching Frequency | 100 kHz to 2 MHz - enables optimization of inductor size vs. efficiency; RT resistor sets frequency with ±10% tolerance. |
| Current Sense Accuracy | ±5% LED current - achieved via trimmed transconductance error amplifier and low-drift IADJ-to-ISENSE scaling (VIADJ/6). |
| Integrated MOSFET RDS(on) | 220 mΩ @ VBOOT–VPH = 6 V - reduces external component count and improves thermal efficiency in compact layouts. |
| Dimming Interface | Dual analog (IADJ) + PWM (PDIM) - enables >10:1 analog contrast and >100:1 PWM contrast without compromise or external circuitry. |
| UVLO Threshold | Adjustable via resistor divider on UVLO pin - rising threshold 1.12–1.30 V; hysteresis enabled by 2.9 µA current source for reliable start/stop control. |
Pinout & Package
HVSSOP-10 package with exposed PowerPAD™ thermal pad (5.00 mm × 3.00 mm); requires direct PCB copper connection to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT | Bootstrap supply node | Drives high-side MOSFET gate; requires 0.1 µF ceramic capacitor between BOOT and PH to sustain gate drive during conduction. |
| VIN | Main power input | Accepts 4.5–60 V DC; powers internal regulators and high-side switch; must be bypassed with ≥10 µF low-ESR capacitor. |
| UVLO | Enable/hysteresis control | Resistor-divider input sets start/stop voltage; internal 1 µA pull-up ensures default ON; 2.9 µA hysteresis current enables clean turn-on/off. |
| PDIM | PWM dimming input | Directly controls gate driver enable/disable; compatible with 1.34–1.45 V logic HIGH; 0.79–0.88 V logic LOW; 1 µA pull-up maintains default ON state. |
| RT/CLK | Frequency programming/sync | Configurable as RT resistor input (0.5 V regulated) or high-impedance CLK sync input (1.49–1.81 V threshold); PLL locks within 100 µs. |
| PH | Switch node | Source of internal high-side MOSFET; connects to inductor and LED cathode; requires low-inductance layout to minimize ringing and EMI. |
| GND | Power and signal ground | Common reference for all analog/digital circuits; must be tied directly to exposed PowerPAD™ for thermal dissipation and noise immunity. |
| COMP | Error amplifier output | Connects to RC compensation network; 0.1 µF capacitor to GND provides stable loop response; clamped at ~2.2 V during overcurrent. |
| ISENSE | Current sense input | Inverting input of transconductance error amplifier; monitors voltage across external sense resistor; accuracy depends on IADJ voltage stability. |
| IADJ | Analog current setpoint | 0–1.8 V input scales ISENSE reference to VIADJ/6; 180–1800 mV range yields 10:1 dimming ratio with ±5% current accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Dual dimming interface | Independent analog (IADJ) and PWM (PDIM) inputs enable simultaneous use-e.g., coarse analog trim + fine PWM modulation-without interaction or calibration drift. |
| Programmable frequency sync | RT/CLK pin switches automatically between resistor-set and external clock modes; eliminates beat frequencies in multi-driver systems and simplifies EMI filter design. |
| Integrated thermal protection | 165°C shutdown with 20°C hysteresis prevents latch-up; resumes operation only after die cools below 145°C-ensures robustness in enclosed luminaires or high-ambient environments. |
| High-side MOSFET integration | 220-mΩ RDS(on) at 6 V VGS reduces BOM count and PCB area; eliminates need for external high-voltage gate driver and associated level-shifting components. |
| UVLO with hysteresis | User-configurable start/stop thresholds via single resistor divider; internal 2.9 µA hysteresis current eliminates oscillation near threshold-critical for battery-powered or unstable input applications. |

FAQ
What is the maximum input voltage supported by the TPS92513HVDGQR?
The TPS92513HVDGQR supports an absolute maximum input voltage of 65 V and a recommended operating range of 4.5 V to 60 V. This 60 V upper limit distinguishes it from the standard TPS92513 (42 V max), making the TPS92513HVDGQR suitable for 48 V DC systems with transient headroom, such as PoE++-powered luminaires or industrial 60 V rail applications.
How does the IADJ pin function in the TPS92513HVDGQR?
The IADJ pin on the TPS92513HVDGQR sets the LED current reference voltage at the ISENSE pin using the relationship VISENSE = VIADJ/6. With an input range of 0 V to 1.8 V, it produces a corresponding ISENSE voltage from 0 mV to 300 mV-enabling precise analog dimming across a 10:1 range. The TPS92513HVDGQR maintains ±5% LED current accuracy when VIADJ is between 180 mV and 1.8 V.
Can the TPS92513HVDGQR synchronize its switching frequency to an external clock?
Yes, the TPS92513HVDGQR can synchronize its switching frequency using the RT/CLK pin. When driven with a square wave transitioning below 0.63 V and above 1.81 V, the device enters PLL mode with lock-in time ≤100 µs. The TPS92513HVDGQR supports synchronization from 300 kHz to 2 MHz and automatically reverts to resistor-programmed mode if the external clock stops.
What thermal considerations apply to the TPS92513HVDGQR in HVSSOP package?
The TPS92513HVDGQR in DGQ (HVSSOP-10) package has a junction-to-board thermal resistance (RθJB) of 37.5°C/W and requires direct connection of the exposed PowerPAD™ to a large GND copper area. For 1.5 A operation at 60 V input, thermal design must maintain TJ ≤125°C; derating is advised above 85°C ambient unless enhanced heatsinking is implemented.
Does the TPS92513HVDGQR support both analog and PWM dimming simultaneously?
Yes, the TPS92513HVDGQR supports independent analog dimming via the IADJ pin and PWM dimming via the PDIM pin. These interfaces operate concurrently without interference-the IADJ pin sets the current reference level while PDIM modulates the duty cycle of the high-side switch. This dual-path architecture enables >100:1 total dimming ratio in applications like architectural lighting where fine-grained control is essential.
