Product details
Overview
HV9910BNG-G from Microchip Technology is an open-loop, peak current mode LED driver controller IC designed for buck topology LED drivers. It operates with 8.0–450 V DC input, delivers 7.5 V regulated VDD, supports constant frequency or constant off-time operation, and enables both linear (0–250 mV LD input) and PWM dimming (0–100% duty, kHz-range) - deployed in flat-panel display backlighting and signage LED systems.
For engineers reviewing the HV9910BNG-G datasheet, HV9910BNG-G pinout, HV9910BNG-G application, or HV9910BNG-G equivalent, this page provides verified technical context, real-world design meaning of key specs, validated 16-lead SOIC pin functions, confirmed alternative options for LED driver control, and supply-chain support for industrial lighting BOMs.
Technical Context
The HV9910BNG-G implements open-loop peak current control using dual comparators-one referenced to internal 250 mV, the other to the LD pin-whose outputs feed an OR gate that resets an SR flip-flop to terminate each switching cycle. Its oscillator is resistor-programmable via RT pin, supporting either constant-frequency mode (RT-to-GND) or constant off-time mode (RT-to-GATE), with no slope compensation required in the latter.
It integrates an 8.0–450 V linear regulator delivering 7.5 V ±0.25 V at VDD with ≤100 mV load regulation and ≤1.0 V line regulation across full input range. The GATE driver sources/sinks 165 mA with 30–50 ns rise/fall times into 500 pF, enabling direct drive of low-QG MOSFETs (≤15 nC above 100 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 8.0–450 V DC - powers directly from high-voltage DC rails without auxiliary supply |
| VDD regulation | 7.5 V ±0.25 V - stable internal supply for logic and gate driver; eliminates need for external LDO |
| Oscillator frequency | 20–30 kHz (RT = 1 MΩ) or 80–120 kHz (RT = 226 kΩ) - sets switching frequency or off-time per configuration |
| Current sense threshold | 250 mV typ (internal) or adjustable down to 0 V via LD pin - defines peak inductor current limit |
| GATE drive capability | 165 mA sink/source, 30–50 ns edge times - drives MOSFETs with QG ≤15 nC at >100 kHz |
| PWM dimming input | 0–100% duty, up to few kHz - enables fast LED current on/off control with minimal inductor-current-dependent delay |
| Linear dimming input | 0–250 mV at LD pin - scales current sense threshold to adjust LED current proportionally |
Pinout & Package
HV9910BNG-G is packaged in a 16-lead narrow-body SOIC (NG) with 1.27 mm pitch, 9.90 × 3.90 mm body, and Pb-free matte tin finish (ROHS-compliant). Pin 1 is located at the index area per JEDEC MS-012 AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | High-voltage input | Accepts 8.0–450 V DC; powers internal linear regulator - no external bias supply needed |
| 4 (CS) | Current sense comparator input | Detects FET current via external RCS; triggers GATE turn-off when ≥250 mV or LD voltage |
| 5 (GND) | Power ground reference | Common return for internal circuits and power train - must connect to power-stage ground plane |
| 8 (GATE) | External MOSFET gate driver output | Drives N-channel FET gate; 165 mA drive strength supports fast switching with low-QG devices |
| 9 (PWMD) | PWM dimming enable/disable | Pull to GND disables GATE output instantly; pull to VDD enables normal operation |
| 12 (VDD) | Internal regulator output / external supply input | 7.5 V regulated output (bypass ≥0.1 μF); can accept external 7.5–12 V supply to disable internal regulator |
| 13 (LD) | Linear dimming / current threshold control | Sets CS trip point from 0–250 mV; allows precise LED current scaling without changing RCS |
| 14 (RT) | Oscillator timing resistor connection | Resistor to GND → constant frequency mode; resistor to GATE → constant off-time mode |
| 2,3,6,7,10,11,15,16 | No-connect (NC) | Not bonded internally - must remain unconnected in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Open-loop peak current control | Eliminates loop compensation components and stability analysis - reduces bill-of-materials and design cycle time |
| Integrated 8–450 V linear regulator | Enables single-supply operation from wide-input DC rails - removes need for auxiliary low-voltage supply |
| Configurable constant frequency or constant off-time mode | Switching behavior selected by one external resistor connection - supports input-voltage-insensitive current regulation (COT) or fixed-frequency EMI management (CF) |
| Independent linear and PWM dimming inputs | LD pin adjusts current setpoint (0–250 mV); PWMD pin enables/disables output (0/1 logic) - supports hybrid dimming strategies |
| Fast 80 ns comparator response + 150–280 ns blanking | Prevents false triggering from switch-node noise while preserving fast current-sense reaction - improves reliability in noisy buck layouts |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL8862T-13 | Fixed 1 MHz switching frequency; requires external VDD supply; no integrated HV regulator | Better suited for low-input-voltage (≤30 V) buck designs where high-frequency operation reduces inductor size | Select AL8862T-13 when board space is constrained and input voltage is stable and low; HV9910BNG-G remains preferred for wide-input, single-supply, cost-sensitive designs |
| MPQ3367-AEC1 | Automotive-grade AEC-Q100 qualified; includes fault protection (OVP, OTP, LED short/open); requires external current sense amplifier | Targeted at automotive interior lighting with safety-critical diagnostics and robustness requirements | Choose MPQ3367-AEC1 only for automotive programs requiring AEC-Q100 compliance; HV9910BNG-G offers lower BOM cost and simpler layout for industrial/commercial use |
Compared with AL8862T-13 and MPQ3367-AEC1, HV9910BNG-G uniquely combines ultra-wide input voltage support (8–450 V), integrated HV regulator, and dual dimming modes in a single 16-pin SOIC - making it optimal for cost-driven, high-input-voltage LED driver designs without automotive or high-frequency constraints.

FAQ
What is the maximum input voltage rating for HV9910BNG-G?
HV9910BNG-G has an absolute maximum VIN-to-GND rating of +470 V, with functional operation specified from 8.0 V to 450 V DC. At 450 V, thermal limits constrain continuous operation unless external power dissipation measures (e.g., series Zener) are applied - refer to thermal resistance θja = 83°C/W for the 16-lead SOIC package when calculating junction temperature rise.
Does HV9910BNG-G require external loop compensation components?
No, HV9910BNG-G uses open-loop peak current mode control, eliminating the need for external compensation networks. Its architecture relies on inherent current-sense timing and blanking to regulate LED current without feedback loop stability analysis - reducing component count and design complexity compared to closed-loop controllers.
How does the RT pin configure constant frequency versus constant off-time operation in HV9910BNG-G?
In HV9910BNG-G, connecting the RT pin to GND configures constant frequency mode (oscillator period determined by RT value); connecting RT to GATE configures constant off-time mode (off-time determined by RT value). This single-resistor reconfiguration enables input-voltage-insensitive current regulation (COT) or fixed-frequency EMI control (CF) without changing IC or layout.
Can HV9910BNG-G drive high-side or low-side MOSFET configurations?
HV9910BNG-G is designed for low-side N-channel MOSFET drive in buck topology - its GATE output is referenced to GND and cannot float above VIN. It does not support high-side drive or bootstrap gate driving; for high-side applications, a dedicated high-side driver or different controller topology is required.
What is the minimum LED current achievable using the LD and PWMD pins on HV9910BNG-G?
With LD = GND, HV9910BNG-G maintains a minimum on-time (~450 ns) due to blanking + delay, resulting in non-zero residual LED current dependent on input voltage, inductance, and LED forward voltage. To achieve true zero current, PWMD must be pulled to GND - which forces immediate and complete GATE turn-off regardless of internal timing.
