Product details
Overview
HV96001-E/D7X from Microchip Technology is a secondary-side, micro-interfaced, flicker-free LED controller IC for offline lighting systems requiring wide-range analog and PWM dimming. It integrates flyback and boost converter control, 8V–60V input operation, 200 kHz fixed switching frequency, and supports PWM dimming down to 0.01% duty cycle with <150 ns pulse width - enabling high-fidelity dimming in architectural and commercial LED luminaires.
For engineers reviewing the HV96001-E/D7X datasheet, HV96001-E/D7X pinout, HV96001-E/D7X application, or HV96001-E/D7X equivalent, this device delivers precise LED current regulation across wide load voltage ranges, headroom-optimized flyback/boost coordination, and robust fault protection including stuck-at-zero DIM detection, overvoltage, overcurrent, and short-circuit recovery with auto-retry timing.
Technical Context
The HV96001-E/D7X implements dual-loop regulation: a flyback regulator (FRO) with three transconductance error amplifiers (low/high-gain + recovery) controls output voltage to maintain optimal headroom for the boost stage, while a dedicated boost regulator (BRO) with fast-slew error amplifier and DIM-synchronized disconnect logic governs LED current amplitude. Its architecture enables stable current regulation even during sub-150 ns PWM pulses by minimizing propagation delay (<110 ns BCS-to-BSG), reducing leakage-induced drift via high transconductance (1.0 mA/V BRO), and using active blanking (750 ns LCS, 30–80 ns BCS).
It features galvanically isolated feedback via integrated optocoupler driver (OPT), dual reference thresholds (e.g., VHRFROH = 1.5 V for headroom recovery), and adaptive mode transitions - start-up prioritizes minimum supply voltage (VMSFROH = 1.0 V), steady-state uses headroom regulation (VHFROL = 1.0 V), and transient overload triggers recovery amplification. All regulators operate across –40°C to +125°C ambient.

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 NCL30488 | Single-stage flyback controller only; no integrated boost regulator or load switch gate driver - requires external boost stage for zero-ripple current. | Best suited for cost-sensitive, lower-power (<60 W) designs where 120 Hz ripple is acceptable; lacks HV96001-E/D7X's sub-150 ns PWM capability. | Select when system-level ripple rejection is relaxed and BOM cost is prioritized over dimming fidelity. |
| Diodes Incorporated AL1676 | Primary-side controlled flyback IC with analog dimming only; no secondary-side sensing, no PWM dimming support below 1%, no headroom optimization. | Targets basic retrofit lamps and simple constant-current drivers; cannot implement the HV96001-E/D7X's flicker-free multi-stage architecture. | Select for non-isolated, low-complexity applications where galvanic isolation and deep PWM dimming are not required. |
Compared with NCL30488 and AL1676, the HV96001-E/D7X uniquely integrates secondary-side boost regulation, headroom-adaptive flyback control, and sub-150 ns PWM timing - making it the only solution capable of achieving IEC TR 61547-1 Class A flicker immunity in high-power, wide-input offline LED drivers.

FAQ
What is the minimum PWM dimming pulse width supported by the HV96001-E/D7X?
The HV96001-E/D7X supports PWM dimming pulses as narrow as 75 ns (typical minimum to initiate boost switching) and maintains stable LED current regulation down to 150 ns and lower. This capability is enabled by its low-propagation-delay BCS-to-BSG path (<110 ns), fast BRO amplifier (50 µs 90% rise time), and dedicated DIM-synchronized disconnect logic - ensuring flicker-free operation in premium architectural lighting applications where the HV96001-E/D7X is deployed.
How does the HV96001-E/D7X manage headroom voltage between flyback and boost stages?
The HV96001-E/D7X continuously monitors headroom voltage via the HVS pin and uses a dedicated headroom voltage error amplifier (VHFROL = 1.0 V) to dynamically adjust the flyback output voltage. This keeps the boost converter's input-to-output differential minimal - reducing conduction losses, enabling smaller magnetics, and sustaining >90% system efficiency across LED string voltages from 10 V to 60 V. The HV96001-E/D7X implements this without external compensation components.
Does the HV96001-E/D7X require an external optocoupler, and how is it interfaced?
Yes, the HV96001-E/D7X requires an external optocoupler for primary-side feedback isolation, but it integrates a dedicated optocoupler driver (OPT pin) that provides push-pull output (0.75–4.2 V) with 5 mA drive capability - eliminating external transistor buffers or level shifters. The OPT pin connects directly to the optocoupler LED anode, while the cathode ties to FRO, enabling seamless galvanic isolation in offline LED drivers using the HV96001-E/D7X.
What protection features are built into the HV96001-E/D7X?
The HV96001-E/D7X integrates six independent protection mechanisms: (1) VDD and SUP undervoltage lockout, (2) LED load overvoltage detection (OVS), (3) boost/LED overcurrent detection (BCS/LCS), (4) short-circuit protection with auto-retry delay, (5) DIM stuck-at-zero detection with restart, and (6) headroom undervoltage monitoring (HVS). All protections trigger controlled shutdown and programmable retry via the TMR pin capacitor - enhancing reliability in harsh environments where the HV96001-E/D7X operates.
Can the HV96001-E/D7X operate with both analog (linear) and PWM dimming simultaneously?
No - the HV96001-E/D7X supports either analog dimming (via LCR pin voltage 0–400 mV) or PWM dimming (via DIM pin square wave), but not simultaneous use. When DIM is held high or low, analog dimming is active; when DIM receives a PWM signal, the IC enters digital dimming mode and disables LCR-based amplitude control. This functional separation ensures predictable behavior and avoids conflicting control signals in systems deploying the HV96001-E/D7X.
