Product details
Overview
HV98101T-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 230 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 HV98101T-E/CH datasheet, HV98101T-E/CH pinout, HV98101T-E/CH application, or HV98101T-E/CH equivalent, this page provides verified technical context, validated pin functions, real-world LED current control behavior, and confirmed alternative options for 230 VAC LED driver designs requiring low THD and high PF without auxiliary windings.
Technical Context
The HV98101T-E/CH employs a proprietary control scheme that dynamically modulates both on-time and switching period across the AC line cycle to enforce input current proportionality to input voltage-enabling simultaneous high power factor (0.97 typ.) and low THD (5% typ.) independent of LED string voltage. It operates exclusively in boundary conduction mode (BCM) and uses valley detection via the IND pin to minimize switching losses.
Startup relies on external resistor RHV charging CPVDD; once PVDD reaches 14.5–17.5 V, the IC initiates 10 kHz fixed-frequency switching until valley detection locks, then transitions to adaptive valley-switching. LED current is regulated closed-loop using internal 204 mV reference (CSREF), transconductance amplifier (gm = 160–300 μA/V), and COMP pin compensation network.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 230 VAC ±15% - fixed-line design; not universal-input capable |
| Output Power Range | 5–15 W - supports single-stage buck-boost LED drivers without PFC stage |
| LED Current Accuracy | Better than ±5% - achieved via closed-loop regulation with 204 mV internal CSREF |
| Power Factor | 0.97 (typical) - meets IEC 61000-3-2 Class C requirements for lighting equipment |
| Total Harmonic Distortion | 5% (typical) - enabled by novel time-varying control, not constant on-time |
| Valley Detection | Uses IND pin with 4.3 V threshold and 450 μA overvoltage trip - eliminates need for auxiliary winding |
| Package | SOT-23-6L - thermally rated at θJA = 124 °C/W; supports compact board layouts |
Pinout & Package
HV98101T-E/CH is housed in a space-saving 6-lead SOT-23 package with exposed pad thermal enhancement per JEDEC MO-178. Pin 1 (IND) serves dual valley-sensing and overvoltage protection roles; all pins require proper PCB layout shielding (especially IND) to prevent mis-triggering from high dv/dt.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IND | Valley detect & overvoltage sense input | Sinks current when GATE is low; 450 μA trip triggers shutdown; requires shielded trace routing |
| 2 - GND | Power and signal reference ground | Must be low-impedance star point for PVDD capacitor, COMP network, and CS resistor |
| 3 - COMP | Transconductance amplifier output | Connects external RC network to stabilize LED current loop; sets bandwidth via GBW = 0.16–0.24 MHz |
| 4 - CS | Inductor current sense input | Monitors RCS voltage drop to regulate average LED current; includes leading-edge blanking (150–250 ns) |
| 5 - PVDD | IC supply voltage input | Clamped at 15.5–18.5 V; requires ≥4.7 μF ceramic capacitor placed adjacent to pin |
| 6 - GATE | External MOSFET gate driver output | Drives high-side switch with 0.3 A source / 0.6 A sink capability; TRISE ≤ 45 ns, TFALL ≤ 23 ns |
Key Features
| Feature | Design Value |
|---|---|
| Valley-switching buck-boost topology | Reduces MOSFET turn-on loss without resonant components or auxiliary windings |
| Integrated PFC with low THD | 0.97 PF and 5% THD maintained across full line/load range - no external PFC controller needed |
| Bootstrap-free startup & operation | PVDD powered from rectified AC via RHV/DHV; bootstraps from CO during steady-state to sustain VDD,ON–VDD,OFF hysteresis |
| Dual-function IND pin | Enables valley detection and overvoltage protection using same node - cuts BOM count and layout area |
| Robust protection suite | OCP with 2.2–2.5 V reference, OVP via IND current, short-circuit recovery via POR, and thermal shutdown at TJ > 125°C |

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; requires auxiliary winding for VCC; 0.93 PF, 10% THD | Higher THD limits use in Class C-compliant fixtures; needs extra transformer winding | Select if lower BOM cost outweighs THD/PF trade-off and auxiliary winding is acceptable |
| Diodes Incorporated AL1676-10TR | Valley-switching buck-boost; 230 VAC version; 0.95 PF, 7% THD; no IND pin - separate OVP required | Lacks integrated valley/OVP dual function; requires external OVP circuit and larger compensation network | Choose when needing higher peak current drive (1.2 A GATE) but accepting added component count and layout complexity |
Compared with HV98101T-E/CH, NCL30001DR2G offers lower gate drive strength and higher THD, while AL1676-10TR provides stronger gate drive but lacks the IND pin's dual valley/OVP functionality-increasing bill-of-materials and reducing layout simplicity in space-constrained LED lamp designs.

FAQ
What is the input voltage specification for HV98101T-E/CH?
HV98101T-E/CH is rated for 230 VAC ±15% input only - it is not a universal-input device. The HV98100 variant supports 110 VAC ±15%. Attempting to operate HV98101T-E/CH on 110 VAC will result in insufficient PVDD startup voltage and failure to initiate switching. Designers must select the correct variant per regional mains voltage.
Does HV98101T-E/CH require an auxiliary winding on the inductor?
No, HV98101T-E/CH does not require an auxiliary winding. Its bootstrap circuit derives PVDD supply from the output capacitor (CO) via RPVDD-DPVDD during steady-state operation, and initial startup is handled by the external RHV-DHV network. This eliminates auxiliary winding complexity and cost - a key differentiator versus competing controllers.
How does HV98101T-E/CH achieve low THD while maintaining high power factor?
HV98101T-E/CH uses a proprietary time-varying control algorithm that simultaneously adjusts on-time and switching frequency across the AC line cycle - forcing input current to track input voltage waveform. Unlike constant on-time schemes, this method maintains 5% THD and 0.97 PF across all load and line conditions without dependency on LED string voltage.
What protection features are integrated into HV98101T-E/CH?
HV98101T-E/CH integrates overvoltage protection (OVP) triggered by >450 μA current into the IND pin, overcurrent protection (OCP) referenced to 2.2–2.5 V at CS, leading-edge blanking (150–250 ns), and thermal shutdown at TJ > 125°C. It also features automatic restart after fault clearance and valley-detection lockout during startup or short-circuit events.
Can HV98101T-E/CH drive high-current LEDs above 150 mA?
HV98101T-E/CH regulates average LED current via external RCS resistor and internal 204 mV reference (ILED = 0.204 V / RCS). While the IC itself supports designs up to 15 W, maximum practical LED current depends on external MOSFET, inductor, and thermal design. For currents >150 mA, ensure GATE drive capability (0.6 A sink), PCB copper area, and θJA derating maintain TJ ≤ 125°C under worst-case ambient conditions.
