Product details

Overview

HVLED001BTR from STMicroelectronics is a high-power-factor quasi-resonant flyback controller with primary-side voltage regulation, 800 V high-voltage startup, ultra-low standby consumption (≤600 µA), and integrated input voltage sensing for universal AC input (0–480 V_AC). It enables single- or two-stage LED drivers meeting IEC 61000-3-2 Class C harmonic limits.

For engineers reviewing the HVLED001BTR datasheet, HVLED001BTR pinout, HVLED001BTR application, or HVLED001BTR equivalent, this IC supports PSR/SSR dual-loop operation, programmable frequency foldback via TOFF, burst-mode dimming compatibility (0–10 V / PWM), and smart auto-restart timer (ART) for latch-free recovery after overvoltage, brownout, or open-loop faults.

Technical Context

The HVLED001BTR implements peak current mode control with valley-switching detection (ZCD pin) to achieve quasi-resonant operation, minimizing switching losses across wide load and line ranges. Its internal multiplier integrates HVSU-sensed input voltage with FB/OPTO feedback to maintain high power factor (>0.9) and low THD (<15%) in universal input (85–265 V_AC) applications.

It features dual regulation paths: primary-side regulation (PSR) using ZCD-based output voltage reconstruction (V_REF,PSR = 2.60 V ±50 mV), and secondary-side regulation (SSR) via optocoupler-connected OPTO pin with disconnection detection. Protection logic includes brownout (IBO = 100 µA), OCP (V_CS,lim = 750 mV), and OPP (V_FB = 2.8 V) with timed response (T_OPP = 100 ms).

Key Specifications

Standby Current	≤600 µA in low-consumption mode - meets Energy Star & EU CoC Tier 2 no-load requirements
Power Factor	>0.9 at full load, 85–265 V_AC - achieved via real-time input voltage sensing and adaptive current shaping
Regulation Accuracy	±1% on V_REF,PSR (2.60 V) for PSR; ±1.5% on V_OPTO,bias (3.2 V) for SSR - ensures stable LED current under line/load transients

Pinout & Package

Package: SSOP10 (3.9 mm × 4.9 mm, 0.65 mm pitch), RoHS-compliant, surface-mount.

Pin/Terminal	Circuit Role	Design Meaning
HVSU (Pin 1)	High-voltage startup & input sensing	Withstands 800 V DC; charges VCC during startup and measures line voltage for PF correction and I-OVP
N.C. (Pin 2)	No connect	Internally unconnected - must remain floating per datasheet
TOFF (Pin 3)	Frequency foldback control	Voltage-programmable blanking time (55–115 µs) to skip valleys and reduce switching frequency at light load
FB (Pin 4)	Primary-side regulation output	Drives PSR compensation network; burst mode triggered at V_FB = 1.054 V; OPP threshold at 2.8 V
OPTO (Pin 5)	Secondary-side feedback input	Accepts optocoupler collector; disables regulation if pulled below 1.054 V - enables feedback loss detection
ZCD (Pin 6)	Zero-current detection & multi-sense	Detects MOSFET turn-on point; senses output voltage (PSR) and input brownout (IBO = 100 µA)
CS (Pin 7)	Current sense comparator input	Monitors primary current; triggers OCP at 750 mV; includes 340 ns leading-edge blanking
GND (Pin 8)	Signal reference	Common return for all analog/digital blocks; requires low-inductance PCB layout to avoid noise coupling
GD (Pin 9)	Gate driver output	0.66 A source / 1.2 A sink capability; drives MOSFET/IGBT gates directly - eliminates external driver need
VCC (Pin 10)	Supply rail	UVLO thresholds: turn-on at 13.2 V, low-consumption entry at 7.9 V, reset at 6.84 V

Key Features

Feature	Design Value
Integrated 800 V HVSU	Eliminates startup resistor and auxiliary winding - reduces BOM count and improves reliability in high-voltage LED drivers
Smart Auto-Restart Timer (ART)	Guarantees automatic recovery from fault conditions (OVP, BO, OCP) without latching - avoids manual reset in field-deployed luminaires
Dual regulation architecture	Independent PSR and SSR loops allow flexible topology selection - PSR for cost-sensitive designs, SSR for high-accuracy constant-current output
Programmable burst-mode dimming	Two burst thresholds (V_FB = 1.054 V / 0.9 V) enable smooth 0–10 V analog dimming and clean PWM dimming down to 1% duty cycle
Multi-protection suite	Simultaneous brownout (75–125 µA), OPP (2.8 V FB clamp), OCP (1.1 V CS), and output OVP detection - meets IEC 62368-1 safety requirements

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-power-factor LED controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NCL30002DR2G	Fixed-frequency CRM (not QR); no integrated HVSU - requires external startup circuit; lower max input voltage (650 V)	Lacks programmable frequency foldback and ART recovery; suitable only for fixed-line applications without brownout risk	Select when cost sensitivity outweighs efficiency and surge robustness - adds 3 external components vs. HVLED001BTR's integrated HVSU
Diodes Incorporated AL1676S16-13	QR controller with 650 V HVSU; no PSR capability - relies solely on optocoupler feedback; lacks 0–10 V dimming support	Cannot implement single-stage PSR topologies; requires secondary-side bias winding and optocoupler - increases size and cost	Choose for SSR-only designs where PSR simplification is unnecessary and 800 V surge immunity is not required

Compared with NCL30002DR2G and AL1676S16-13, HVLED001BTR uniquely combines 800 V HVSU, PSR+SSR dual regulation, and ART-based fault recovery - enabling smaller, safer, and more adaptable LED drivers for universal-input outdoor and industrial lighting.

FAQ

What is the maximum AC input voltage supported by HVLED001BTR?

HVLED001BTR supports universal AC input up to 265 V_AC (≈375 V_DC peak), with HVSU pin rated for 800 V DC and surge protection threshold at 570 V. Input voltage detection remains linear up to 480 V_DC, enabling robust operation in 277 V_AC and 347 V_AC industrial systems without external scaling resistors.

How does the Smart Auto-Restart Timer (ART) function differ from conventional latch-off protection?

ART implements a non-latching, self-timed recovery: after detecting OVP, brownout, or OCP, the IC enters stop mode for 2.5 s (typical T_rec), then automatically reinitiates startup sequence without external intervention. Unlike latch-off ICs requiring power cycle or pin reset, ART maintains system uptime in transient grid events - critical for outdoor lighting and industrial automation.

Can HVLED001BTR operate in both primary-side and secondary-side regulated modes simultaneously?

No - HVLED001BTR supports independent PSR or SSR operation, not concurrent dual-loop regulation. PSR uses ZCD pin for output voltage reconstruction; SSR uses OPTO pin for optocoupler feedback. The internal OR logic combines FB and OPTO signals for multiplier input, but only one loop dominates regulation based on external circuit configuration and pin biasing.

What is the minimum recommended output power for stable burst-mode dimming?

Stable burst-mode dimming begins at ≥5% of full-scale output power. Below this level, the IC may enter low-consumption mode instead of controlled burst operation. For reliable 0–10 V dimming down to 1%, design the transformer turns ratio and ZCD network to ensure V_ZCD,trig (0.2 V typ.) is consistently exceeded even at lowest load - verified via DS12748 Figure 11 and Section 7.2.4.
