Product details
Overview
ILD6070XUMA1 from Infineon Technologies is a high-efficiency step-down LED driver IC designed for constant-current regulation of high-power LEDs. It operates from 4.5 V to 60 V input, delivers up to 0.7 A average output current, supports up to 1 MHz switching frequency, and integrates analog/PWM dimming control with ±3% LED current accuracy over temperature. It is used in street lighting, downlights, and LED ballasts requiring robust thermal management and stable current drive.
For engineers reviewing the ILD6070XUMA1 datasheet, ILD6070XUMA1 pinout, ILD6070XUMA1 application, or ILD6070XUMA1 equivalent, key selection criteria include input voltage range (4.5–60 V), output current capability (0.7 A), integrated dimming interface (analog + PWM), over-temperature protection adjustability, and PG-DSO-8-27 thermal package performance.
Technical Context
The ILD6070XUMA1 implements a synchronous buck topology with internal high-side and low-side MOSFETs, enabling high efficiency across wide input ranges. Its integrated PWM generator converts analog dimming voltage (0–1.25 V) into precise duty-cycle-modulated LED current, while digital PWM input accepts 100 Hz–20 kHz signals for direct brightness control.
It features programmable over-temperature protection via external resistor on RTadj, undervoltage lockout at 4.0 V (typ.), and cycle-by-cycle over-current protection triggered at 1.1 A (typ.) peak switch current. Thermal shutdown activates at TJ ≥ 150 °C (typ.), with hysteresis set by RTadj.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 60 V - supports wide-range DC inputs including 12 V, 24 V, and 48 V industrial bus rails. |
| Max Output Current | 0.7 A average - sufficient for driving multi-chip LED arrays in downlight and streetlight modules. |
| Switching Frequency | Up to 1 MHz - enables compact magnetics and reduced EMI filter size without sacrificing efficiency. |
| LED Current Accuracy | ±3% (typ.) - ensures consistent luminance across production units and temperature (-40 °C to +125 °C). |
| Dimming Interface | Analog (0–1.25 V) + digital PWM (100 Hz–20 kHz) - supports both legacy analog control and modern microcontroller-based dimming. |
| Over-Temp Protection | Adjustable via RTadj pin (125–150 °C range) - allows system-level thermal derating aligned with heatsink design. |
| UVLO Threshold | 4.0 V (typ.) - prevents erratic startup during brown-out conditions in unregulated DC supplies. |
Pinout & Package
The ILD6070XUMA1 is housed in a thermally enhanced PG-DSO-8-27 package (exposed thermal pad, 8-pin SOIC variant), optimized for PCB heat dissipation in high-power LED applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply voltage | Accepts 4.5–60 V DC; connects to bulk capacitor and input EMI filter. |
| GND | Power and signal ground | Common reference for all internal circuits and external sense resistors. |
| SW | Switch node | Drives external inductor; connects to internal high-side/low-side MOSFETs. |
| FB | Current-sense feedback | Monitors voltage across external sense resistor to regulate average LED current. |
| PWM | Dimming control input | Accepts analog voltage (0–1.25 V) or digital PWM signal for brightness control. |
| RTadj | Over-temperature threshold adjust | Resistor-to-ground sets thermal shutdown temperature (125–150 °C range). |
| VS | Bias supply monitor | Internal LDO input; must be connected to VIN for proper gate driver operation. |
| EN | Enable control | Active-high logic input; disables IC and reduces quiescent current to <10 µA. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous buck architecture | Integrated high-side and low-side MOSFETs eliminate external sync rectifier, reducing BOM count and conduction loss. |
| Soft-start function | Internally controlled ramp-up of LED current prevents inrush stress on LEDs and input capacitors. |
| Thermally optimized PG-DSO-8-27 | Exposed thermal pad lowers RthJA to 60 K/W (typ.) on 2-layer 2 oz Cu PCB, enabling 0.7 A continuous operation without forced air. |
| Programmable over-temperature protection | RTadj pin allows precise alignment of thermal shutdown threshold with system-level thermal design, avoiding premature shutdown. |
| Dual dimming interface | Single PWM pin accepts either analog voltage or digital PWM - simplifies system integration across multiple controller platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3409MH/NOPB (TI) | External MOSFET required; no integrated PWM generator; 1.25 V FB reference vs. ILD6070's current-sense architecture. | Requires additional components for analog dimming; better suited for designs needing >1 A output or custom gate drive timing. | Select when higher output current or discrete FET control is needed; avoid if minimizing BOM count is critical. |
| AL8862SP-13 (Diodes Inc.) | Fixed 120 kHz switching frequency; no adjustable over-temperature protection; smaller SO-8 package (no exposed pad). | Limited thermal headroom above 0.5 A; lacks RTadj flexibility for system-level thermal co-design. | Prefer for cost-sensitive, lower-power (<0.5 A) indoor lighting where thermal margin is ample. |
Compared with LM3409MH/NOPB and AL8862SP-13, the ILD6070XUMA1 provides integrated power switches, programmable thermal protection, and dual-mode dimming in a thermally robust package-making it optimal for 0.7 A, 60 V-class outdoor and commercial LED drivers where reliability and design simplicity are prioritized.

FAQ
What is the recommended minimum inductance for 0.7 A LED current?
Per Figure 8 of the datasheet, the minimum inductance is 47 µH at 1 MHz switching frequency and 60 V input. Lower inductance increases peak switch current and ripple, risking over-current protection activation and reduced efficiency. Use shielded power inductors rated for ≥1 A saturation current.
How does the RTadj pin configure over-temperature protection?
RTadj sets the thermal shutdown threshold between 125 °C and 150 °C using a single resistor to GND. A 10 kΩ resistor yields ~125 °C; 100 kΩ yields ~150 °C. The relationship is linear per Figure 3, enabling precise alignment with PCB thermal design and heatsink performance.
Can ILD6070XUMA1 drive LEDs in series only, or also in parallel configurations?
The ILD6070XUMA1 is designed for constant-current regulation in series-connected LED strings. Parallel LED strings require individual current-setting resistors or external current mirrors, as mismatched forward voltages cause current imbalance and potential thermal runaway.
Is the PG-DSO-8-27 package RoHS-compliant and halogen-free?
Yes - Infineon confirms the PG-DSO-8-27 package for ILD6070XUMA1 meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21, with lead-free matte tin terminal finish and compliant with JEDEC J-STD-020 moisture sensitivity level 3.
