Product details
Overview
HV96001-E/NFA from Microchip Technology is a secondary-side, micro-interfaced, flicker-free LED controller IC for offline lighting systems. It integrates flyback and boost converter regulation, linear and PWM dimming control (down to 0.01% duty), 200 kHz fixed switching frequency, and dual feedback loops for headroom voltage and LED current amplitude control - enabling high-efficiency, low-ripple LED current in wide-input (8–60 V) applications such as commercial architectural lighting.
For engineers reviewing the HV96001-E/NFA datasheet, HV96001-E/NFA pinout, HV96001-E/NFA application, or HV96001-E/NFA equivalent, this device delivers verified sub-150 ns PWM pulse width support, 100/120 Hz ripple rejection, optocoupler-driven isolated flyback control, and fault recovery with timing-capacitor-set auto-retry - critical for robust, flicker-free dimming in safety-certified AC/DC LED drivers.
Technical Context
The HV96001-E/NFA implements a dual-regulator architecture: a flyback regulator with three transconductance error amplifiers (low/high-gain FRO, headroom recovery) controls output voltage to maintain optimal boost headroom; a boost regulator (BRO) with 65 dB gain and 1 mA/V transconductance precisely regulates LED current via current-mode control. Its DIM input supports both analog amplitude control and digital PWM dimming with dedicated stuck-at-zero detection.
It features integrated gate drivers for boost switch (BSG, 400 mA sink) and load switch (LSG), 10 mA VDD regulator (5 V ±2.5%), and comprehensive protection including overvoltage (OVS), overcurrent (LCS), undervoltage (SVS, VDD, HVS), short-circuit, and thermal monitoring - all operating across –40°C to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 8 V to 60 V - supports universal AC input after rectification and bulk capacitor; enables single design across 100–277 VAC line voltages. |
| PWM Dimming Range | Down to 0.01% duty - enables ultra-deep dimming without visible flicker; validated for pulses <150 ns at up to 20 kHz. |
| Switching Frequency | 200 kHz ±10% - fixed-frequency operation simplifies EMI filtering; allows compact magnetics and reduces audible noise. |
| VDD Output | 5.075 V typical @ 10 mA - powers external circuitry (e.g., optocoupler, bias networks); regulated from same 8–60 V input. |
| Operating Temperature | –40°C to +125°C - qualified for enclosed, thermally demanding luminaires and industrial outdoor lighting. |
| Headroom Control | Adjusts flyback output to minimize boost step-up ratio - reduces boost inductor size, conduction losses, and improves system efficiency across varying LED string voltages. |
| Protection Functions | Integrated OVS, LCS, SVS, VDD UVLO, HVS UVLO, short-circuit, DIM stuck-at-zero - eliminates need for discrete protection ICs and reduces BOM count. |
Pinout & Package
HV96001-E/NFA is available in 16-lead VQFN (3 mm × 3 mm, exposed pad) and 16-lead narrow SOIC packages. Both packages share identical pin numbering and functionality per Microchip DS20006291B.

| DIM (Pin 6 / 4) | PWM/analog dimming input | Accepts 0–5 V square wave or DC; includes 150 kΩ internal pull-down and stuck-at-zero detection. |
| TMR (Pin 7 / 5) | Timing capacitor node | Charges/discharges to set auto-retry delay and DIM fault timeout; requires external capacitor. |
| OPT (Pin 8 / 6) | Optocoupler driver output | Drives optocoupler LED with 4.05 V (typ) high-level and 0.85 V (typ) low-level outputs. |
| FRO (Pin 9 / 7) | Flyback regulator output | Drives OPT pin; provides isolated feedback signal to regulate flyback output voltage. |

| HVS (Pin 14 / 12) | Headroom voltage sense input | Measures boost input–output difference; triggers undervoltage if <0.47 V to prevent boost collapse. |
| BCS (Pin 15 / 13) | Boost current sense input | Senses inductor current; two thresholds (130 mV / 410 mV) enable adaptive peak-current control. |
| BSG (Pin 16 / 14) | Boost switch gate driver | Drives boost MOSFET gate; 400 mA sink capability ensures fast turn-off and reliable switching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCL30160 | Single-stage flyback-only controller; no integrated boost regulator or LSG driver; lacks sub-150 ns PWM support. | Suitable for cost-sensitive, non-flicker-critical applications with limited dimming range (≥1% duty). | Select when system uses single-stage topology and does not require ripple-free current or ultra-deep dimming. |
| Diodes Incorporated AL1676 | Secondary-side controller with boost capability but no dedicated DIM stuck-at-zero detection or 100/120 Hz ripple rejection circuitry. | Targeted at basic dimmable ballasts; requires external components for deep-dimming stability and fault recovery. | Select when design prioritizes footprint over flicker performance and can accommodate external timing/compensation networks. |

FAQ
What is the minimum PWM pulse width supported by HV96001-E/NFA?
HV96001-E/NFA supports PWM dimming pulses as narrow as 75 ns (typical) and is validated for stable operation down to 150 ns - enabling flicker-free dimming to 0.01% duty cycle. This capability is confirmed in Microchip DS20006291B, Figure 2-36 and Section 4.2.2.3, where high-speed circuitry minimizes lag in LED current establishment and sensing.
Does HV96001-E/NFA require an external microcontroller to manage dimming sequences?
No, HV96001-E/NFA operates autonomously without a microcontroller. Its integrated DIM stuck-at-zero detection, timer-based auto-retry, and dual-regulator state logic handle startup, regular operation, and fault recovery independently. The HV96001-E/NFA datasheet confirms full mode control via finite-state machines in Section 4.2 and Figure 3-1 block diagram.
Can HV96001-E/NFA drive multiple LED strings in parallel?
HV96001-E/NFA is designed for single-string LED control with one LSG and one BRO output. Driving multiple strings requires separate HV96001-E/NFA units per string or external current-sharing circuitry - as the IC lacks multi-channel current sensing or synchronization inputs. This limitation is explicit in the Pin Descriptions (Section 3) and Functional Description (Section 4.1).
What package options are available for HV96001-E/NFA?
HV96001-E/NFA is offered in two RoHS-compliant packages: 16-lead VQFN (3 mm × 3 mm, exposed thermal pad) and 16-lead narrow SOIC. Both share identical pinout and electrical specifications per Microchip DS20006291B Page 2 and Package Types table. Thermal impedance differs: RθJA is 46°C/W (VQFN) vs. 63°C/W (SOIC).
How does HV96001-E/NFA achieve 100/120 Hz ripple rejection?
HV96001-E/NFA rejects 100/120 Hz ripple through active regulation: its boost regulator continuously adjusts LED current based on real-time feedback from LCS and LCR pins, while the flyback regulator dynamically trims output voltage to maintain optimal headroom. This closed-loop response - detailed in Section 4.1 and Figure 4-1 - suppresses low-frequency ripple without relying on large bulk capacitors.
