Product details
Overview
HV98100T-E/CH from Microchip Technology is a non-dimmable, off-line LED driver IC implementing valley-switching buck-boost topology with integrated power factor correction (PFC) for 110 VAC ±15% input. It delivers 5–15 W output power with better than 5% LED current regulation accuracy, 0.97 typical power factor, and 5% typical total harmonic distortion (THD), targeting compact LED lamps and lighting fixtures.
For engineers reviewing the HV98100T-E/CH datasheet, HV98100T-E/CH pinout, HV98100T-E/CH application, or HV98100T-E/CH equivalent, key selection criteria include its SOT-23-6L package constraints, valley-sensing IND pin behavior, PVDD startup/stop thresholds (14.5–17.5 V / 6.5–9.5 V), GATE drive capability (0.3 A source / 0.6 A sink), and fixed 110 VAC input compatibility - not universal or 230 VAC operation.
Technical Context
The HV98100T-E/CH employs a proprietary control scheme that dynamically adjusts both on-time and switching period across the AC line cycle to enforce input current proportionality to input voltage - achieving high power factor and low THD independent of LED string voltage. It operates in boundary conduction mode (BCM) and uses valley detection via the IND pin to minimize switching losses.
Startup relies on external RHV resistor charging CPVDD; once PVDD reaches 14.5–17.5 V, the IC begins 10 kHz fixed-frequency switching until valley detection locks, then transitions to valley-switching mode. LED current regulation is closed-loop via CSREF (204 mV typ.) compared against RCS-sensed inductor current, with COMP pin enabling loop stability through external RC compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 110 VAC ±15% - fixed single-line design; not universal or 230 VAC compatible |
| Output Power Range | 5–15 W - supports LED lamps and fixtures up to ~15 W with stable regulation |
| Power Factor | 0.97 (typical) - meets EN61000-3-2 Class C requirements for lighting equipment |
| Total Harmonic Distortion | 5% (typical) - significantly lower than constant-on-time alternatives under varying VO |
| LED Current Accuracy | Better than ±5% - achieved via closed-loop regulation using 204 mV internal CSREF |
| Valley Detection Method | IND pin current sensing (4.3 V clamp, 450 μA OVP threshold) - enables standard off-the-shelf inductor use without auxiliary winding |
| GATE Drive Strength | 0.3 A source / 0.6 A sink - sufficient to drive discrete MOSFETs like MBBT in buck-boost stage |
| Operating Junction Temp | –40°C to +125°C - qualified for enclosed LED fixture environments with thermal derating |
Pinout & Package
HV98100T-E/CH is housed in a space-saving 6-lead SOT-23 package (JEDEC MO-178AA), with θJA = 124°C/W and 800 mW max power dissipation at +25°C ambient. Pin layout is standardized across HV98100/HV98101 variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IND | Valley & over-voltage sense input | Sinks current during GATE-off; 4.3 V clamped; >450 μA triggers OVP shutdown - requires PCB shielding per Figure 3-1 |
| 2 - GND | Power and signal reference ground | Common return for PVDD capacitor, COMP network, and RCS sense resistor - must be star-connected to minimize noise coupling |
| 3 - COMP | Transconductance amplifier output | Drives external RC compensation network to stabilize LED current loop; 1.2–3.8 V swing range defines ILED regulation |
| 4 - CS | Inductor current sense input | Compares RCS voltage against 204 mV internal reference; leading-edge blanking prevents false OCP triggering |
| 5 - PVDD | IC supply voltage input | Accepts 12–18.5 V; internal clamp limits to 15.5–18.5 V; requires ≥4.7 μF ceramic cap placed adjacent to pin |
| 6 - GATE | External MOSFET gate driver output | Drives high-side switch (MBBT); 0.3 A source / 0.6 A sink; TRISE ≤45 ns / TFALL ≤23 ns into 500 pF load |
Key Features
| Feature | Design Value |
|---|---|
| Valley-switching PFC architecture | Reduces MOSFET turn-on loss and EMI; enables >0.97 PF and <5% THD across full line/load range |
| Bootstrap-free PVDD supply | Starts from rectified AC via RHV/DHV; sustains operation via bootstrapping from CO - eliminates auxiliary winding |
| Integrated OVP and short-circuit protection | Detects output overvoltage via IND pin current (>450 μA); enters auto-restart after VDD drops below 6.5–9.5 V |
| Single-stage buck-boost topology support | Enables compact 5–15 W designs with wide VO range (e.g., 88–122 V LED string) using one inductor |
| Robust thermal performance | Rated for –40°C to +125°C junction; 124°C/W θJA allows operation in thermally constrained lamp housings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-dimmable off-line LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCL30001DR2G | Fixed-frequency CCM buck-boost; 0.9 PF, 15% THD; requires auxiliary winding for VCC | Higher THD limits compliance in Class C applications; larger solution size due to auxiliary winding | Prefer HV98100T-E/CH when THD < 7% and auxiliary-winding elimination are mandatory |
| Diodes Incorporated AL8862SP-13 | Valley-switching buck-boost; 0.95 PF, 8% THD; supports 90–305 VAC universal input | Broader input range but higher THD; lacks integrated OVP via IND pin - needs external circuitry | Prefer HV98100T-E/CH for 110 VAC-only designs requiring lowest THD and simplest OVP implementation |
Compared with NCL30001DR2G and AL8862SP-13, the HV98100T-E/CH delivers superior THD (5% vs. 8–15%), eliminates auxiliary winding dependency, and integrates OVP directly into the IND pin - reducing component count and improving reliability in cost-sensitive 110 VAC LED lamp designs.

FAQ
What input voltage range does the HV98100T-E/CH support?
The HV98100T-E/CH supports a fixed single-input range of 110 VAC ±15%. It is not rated for universal input (90–305 VAC) or 230 VAC operation - those require the pin-compatible HV98101 variant. Using HV98100T-E/CH outside its specified 93.5–126.5 VAC range may cause startup failure, regulation loss, or premature OVP shutdown.
How does the HV98100T-E/CH achieve power factor correction without an auxiliary winding?
The HV98100T-E/CH achieves PFC using valley-switching control combined with bootstrap-based PVDD supply from the output capacitor (CO). During normal operation, energy from CO is delivered to PVDD via RPVDD-DPVDD, eliminating need for auxiliary winding or separate bias supply - a key differentiator versus conventional flyback or two-stage drivers.
What is the function of the IND pin on the HV98100T-E/CH?
The IND pin on the HV98100T-E/CH serves dual functions: valley detection and over-voltage protection. When GATE is low, it sinks current proportional to LED string voltage; if current exceeds 450 μA, OVP triggers shutdown. Its 4.3 V clamped voltage and patented sensing method enable reliable valley detection using standard inductors - no auxiliary winding required.
Can the HV98100T-E/CH be used in dimmable LED applications?
No - the HV98100T-E/CH is explicitly designed as a non-dimmable LED driver IC. It lacks dedicated dimming interfaces (e.g., PWM, analog, or DALI inputs) and its control architecture does not support adjustable current scaling. For dimmable 110 VAC solutions, Microchip recommends the HV9910C or third-party alternatives with integrated TRIAC/ELV support.
What thermal considerations apply to the HV98100T-E/CH in enclosed LED fixtures?
The HV98100T-E/CH has a thermal resistance θJA of 124°C/W in SOT-23-6L. In enclosed fixtures, PCB copper area, airflow, and ambient temperature must be managed to keep junction temperature ≤125°C. Derating is required above +85°C ambient; for continuous 15 W operation in sealed housings, supplemental thermal vias or metal-core PCBs are recommended to ensure HV98100T-E/CH reliability.
