Product details
Overview
HV9930LG-G from Microchip Technology is a hysteretic boost-buck (Ćuk) LED driver IC designed for constant-output-current control in low-noise, variable-frequency DC/DC LED lamp drivers. It supports 8–200 V DC input, delivers up to 1 mA VDD supply current, features dual current sensing (CS1/CS2), 7.5 V internal VDD regulation, and PWM dimming with 0–100% duty cycle-ideal for RGB backlight and battery-powered LED lamps.
For engineers reviewing the HV9930LG-G datasheet, HV9930LG-G pinout, HV9930LG-G application, or HV9930LG-G equivalent, this page provides verified technical context, validated pin functions, confirmed Ćuk topology operation, real-world dimming response behavior, and two manufacturer-validated alternative parts for LED driver design continuity.
Technical Context
The HV9930LG-G implements two independent hysteretic comparators-one for input current (CS1) and one for output current (CS2)-with 105 mV turn-on and 20 mV turn-off thresholds, enabling precise current regulation without loop compensation. Its patented AND-gated control logic ensures stable gate drive timing during startup, undervoltage, and overload conditions.
It operates exclusively in Continuous Conduction Mode (CCM) Ćuk topology, supporting both step-up and step-down voltage conversion while decoupling output load from input transients. The internal 8–200 V linear regulator powers VDD at 7.5 V (typ), with UVLO at 6.7 V and 500 mV hysteresis, and REF provides a trimmed 1.25 V ±3% reference for external resistor networks.
Key Specifications

| VDD Regulation | 7.5 V (typ), ±0.5 V - powers internal circuitry and supplies ≤1 mA to external bias networks |
| REF Voltage | 1.25 V ±3% - sets precision current-sense thresholds via external resistor dividers (RCS1/RCS2) |
| GATE Drive Strength | 165 mA sink/source - drives N-channel MOSFETs with 30 ns rise/fall times into 500 pF load |
| PWM Dimming Input | 0–100% duty cycle, 2–5 V high threshold - enables fast, flicker-free brightness control without re-starting converter |

| Junction Temp Limit | +150°C absolute max - defines thermal derating boundary for SOIC package at 101°C/W θJA |
Pinout & Package
Package: 8-lead SOIC (LG), RoHS-compliant, Pb-free matte tin finish, 3300/reel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | High-voltage input to internal regulator | Accepts 8–200 V DC; powers internal VDD regulator; enables single-rail operation without external bias supply |
| CS1 (Pin 2) | Input current sense input | Non-inverting comparator input for input current limiting during startup, undervoltage, or overload |
| GND (Pin 3) | Power and signal ground reference | Mandatory low-impedance connection to power train ground; separates analog and power return paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4425AGU-AEC1-P | Fixed-frequency synchronous buck LED driver; 4.5–40 V input; integrated 0.15 Ω high-side switch; no Ćuk topology support | Requires external boost stage for step-up; lacks dual current sensing; AEC-Q100 qualified but not optimized for cold-crank | Choose for cost-sensitive, fixed-input automotive interior lighting where step-up not required and layout simplicity is prioritized |
| AL8862SP-13 | Asynchronous buck-boost LED controller; 4.5–40 V input; external MOSFET drive; no internal HV regulator or CS1 input | Cannot accept >40 V input directly; needs external bias for VDD; no input current limiting function | Choose for mid-range input applications (<40 V) where Ćuk topology is unnecessary and external HV bias is acceptable |
Compared with MPQ4425AGU-AEC1-P and AL8862SP-13, the HV9930LG-G uniquely supports 8–200 V direct input, dual current sensing for fault-safe operation, and Ćuk topology for ripple cancellation-making it irreplaceable for high-input, step-up/down, and transient-immune LED lamp designs.

FAQ
What topology does the HV9930LG-G support, and why is it significant?
The HV9930LG-G is optimized exclusively for Continuous Conduction Mode (CCM) boost-buck (Ćuk) topology. This configuration enables both step-up and step-down voltage conversion while decoupling the LED load from input transients, reducing input/output current ripple, and allowing shared-core inductors for ripple cancellation-critical for EMI-sensitive and high-reliability LED lamp designs.
How does the HV9930LG-G handle input undervoltage or cold-crank conditions?
The HV9930LG-G incorporates an internal 8–200 V linear regulator with 6.7 V UVLO and 500 mV hysteresis. During cold-crank (e.g., automotive input dropping below 8 V), VIN can be connected to the external MOSFET drain via a diode-leveraging the sum of input and output voltages to maintain VDD regulation and continuous operation without shutdown.
Can the HV9930LG-G drive multiple LED strings independently?
The HV9930LG-G is a single-channel controller with one CS2 input for output current sensing. To drive multiple independent LED strings, separate HV9930LG-G ICs are required-one per string-with individual CS2 feedback paths and shared or independent PWM dimming signals, ensuring precise per-string current regulation and dimming control.
What is the role of the REF pin in HV9930LG-G current programming?
The REF pin delivers a trimmed 1.25 V ±3% reference used to set current-sense thresholds for both CS1 and CS2 comparators. External resistor networks (e.g., RCS1/RS1/RREF1 and RCS2/RS2/RREF2) scale this reference to define input current limit and output LED current levels-enabling accurate, temperature-stable current programming without trimming.
Does the HV9930LG-G require external compensation components?
No. The HV9930LG-G uses a patented hysteretic current-mode control architecture with two independent comparators and AND-gated output logic. This eliminates the need for external compensation components such as type-II or type-III error amplifiers, RC networks, or optocouplers-reducing BOM count, layout area, and design iteration time.
