Product details
Overview
LT8330HS6#TRMPBF from Analog Devices is a current-mode DC/DC converter IC configured as a boost, SEPIC, or inverting regulator with a 1A/60V internal power switch, 6µA quiescent current in Burst Mode, fixed 2MHz switching frequency, and ±40V input voltage range. It delivers stable positive or negative output voltages in automotive-grade industrial power supplies requiring ultra-low standby consumption.
For engineers reviewing the LT8330HS6#TRMPBF datasheet, LT8330HS6#TRMPBF pinout, LT8330HS6#TRMPBF application, or LT8330HS6#TRMPBF equivalent, key selection criteria include its –40°C to 150°C junction temperature rating, TSOT-23-6 package footprint, single FBX-pin topology flexibility, and EN/UVLO threshold accuracy (1.60V rising, 1.56V falling) for robust system-level undervoltage control.
Technical Context
The LT8330HS6#TRMPBF employs fixed-frequency (2MHz) current-mode control with internal compensation, enabling stable operation across 3V–40V input and wide output voltage ranges without external loop components. Its dual-reference feedback architecture supports both positive (1.60V) and negative (–0.80V) regulation via the same FBX pin, eliminating topology-specific design changes.
Thermal lockout at 170°C, frequency foldback during low-VOUT start-up, and integrated soft-start (1ms typical) collectively prevent inductor saturation and output overshoot. The 6µA Burst Mode quiescent current is achieved by fully disabling switching circuitry between pulses while maintaining regulated output voltage with <15mV ripple in typical configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3V to 40V - supports wide-input industrial and automotive battery rails without pre-regulation. |
| Quiescent Current (Burst Mode) | 6µA - enables multi-year battery life in always-on sensor nodes and telematics modules. |
| Switch Rating | 1A continuous, 60V breakdown - handles 48V boost conversion up to 135mA output with margin. |
| Switching Frequency | Fixed 2MHz - permits use of sub-1µH inductors and compact ceramic output capacitors. |
| FBX Regulation Voltage | +1.60V (positive VOUT) or –0.80V (negative VOUT) - single-pin configuration eliminates external reference switching. |
| EN/UVLO Threshold | Rising: 1.68V, Falling: 1.60V - 80mV hysteresis ensures clean power-on/power-off sequencing. |
| Operating Junction Temp | –40°C to +150°C - qualified for under-hood automotive and high-ambient industrial environments. |
Pinout & Package
LT8330HS6#TRMPBF uses the 6-lead Plastic TSOT-23 package (3.0mm × 1.7mm × 1.0mm height), optimized for thermal performance with θJA = 125°C/W. Pin 2 (GND) must be soldered to a PCB ground plane for reliable thermal dissipation and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Supply Connection | Accepts 3V–40V; requires local 4.7µF ceramic bypass placed adjacent to pin for EMI suppression and transient response. |
| INTVCC | Internally Regulated 3V Supply | Powers internal logic and gate driver; must be bypassed with ≥1µF low-ESR ceramic capacitor to GND-no external loading permitted. |
| EN/UVLO | Enable and Undervoltage Lockout Input | Logic-controlled shutdown or programmable UVLO threshold (1.60V/1.68V); draws <1µA when pulled below 0.2V. |
| SW | Internal Power Switch Drain | 60V/1A NMOS drain node; requires minimal trace area and tight layout to reduce radiated EMI and voltage spikes. |
| GND | Power and Signal Ground Reference | Primary return path for switch current and feedback; connects directly to PCB ground plane for thermal and noise control. |
| FBX | Feedback Regulation Input | Single pin accepting either positive (1.60V) or negative (–0.80V) reference; sets output voltage via resistor divider from VOUT. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow Quiescent Current | 6µA in Burst Mode maintains >85% efficiency at 1mA load-critical for battery-powered remote sensors. |
| Topology Flexibility | Single FBX pin supports boost, SEPIC, and inverting configurations without hardware change-reduces BOM count and design cycle time. |
| Automotive Temperature Grade | H-grade (–40°C to +150°C) with AEC-Q100-compliant DFN variants available-meets under-hood thermal requirements. |
| Integrated Protection | Thermal lockout (170°C), frequency foldback during start-up, and soft-start (1ms) prevent inductor saturation and output overshoot. |
| High-Frequency Operation | 2MHz fixed switching enables 0.68µH–10µH inductors and small 4.7µF–15µF ceramic output caps-reducing solution size by >40% vs. 500kHz converters. |
Applications
| Automotive Telematics Power Supply | Industrial Sensor Node DC/DC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT8331EDDB#TRMPBF | 8-lead DFN package, AEC-Q100 qualified, identical electrical specs but includes spread-spectrum modulation for EMI reduction. | Better suited for automotive infotainment where CISPR-25 Class 5 compliance is required; larger footprint than TSOT-23. | Select when EMI certification is mandatory and board space allows DFN; not pin-compatible with LT8330HS6#TRMPBF. |
| TPS61088RHLR | 5.5V max input, 12V max switch, 2.5A switch, no negative output capability, 600kHz–2.2MHz adjustable frequency. | Limited to low-voltage boost only (e.g., USB PD sink); lacks inverting/SEPIC support and automotive temp grade. | Choose for cost-sensitive consumer electronics with ≤5.5V input; unsuitable for 12V+ automotive or bipolar rail generation. |
Compared with LT8330HS6#TRMPBF, LT8331EDDB#TRMPBF adds EMI mitigation at the cost of package size and pinout, while TPS61088RHLR offers higher current but sacrifices input voltage range, topology flexibility, and temperature rating-making LT8330HS6#TRMPBF uniquely balanced for high-temp, multi-topology industrial power.

FAQ
What is the maximum junction temperature rating for LT8330HS6#TRMPBF?
The LT8330HS6#TRMPBF is rated for continuous operation from –40°C to +150°C junction temperature, with thermal lockout activating at 170°C (typical) to protect against sustained overtemperature conditions. This H-grade qualification makes LT8330HS6#TRMPBF suitable for under-hood automotive and high-ambient industrial deployments where standard commercial or industrial grades would fail.
Can LT8330HS6#TRMPBF generate negative output voltages?
Yes, LT8330HS6#TRMPBF supports negative output generation using inverting topology with the same FBX pin, which references –0.80V internally. A resistor divider from VOUT to GND sets the output magnitude, enabling bipolar rail designs (e.g., ±12V) without additional ICs. This capability is confirmed in the device's block diagram and Electrical Characteristics table under FBX regulation voltage.
Does LT8330HS6#TRMPBF require external compensation components?
No, LT8330HS6#TRMPBF features fully internal compensation, eliminating the need for external Type-II or Type-III compensation networks. Its current-mode architecture with fixed 2MHz oscillator and integrated error amplifier ensures stability across all supported topologies (boost, SEPIC, inverting) and input/output combinations without user-adjustable loop components.
What is the purpose of the INTVCC pin on LT8330HS6#TRMPBF?
The INTVCC pin on LT8330HS6#TRMPBF provides a regulated 3V supply for internal circuitry and the gate driver. It must be bypassed with ≥1µF low-ESR ceramic capacitor to GND and cannot be loaded externally. INTVCC enables soft-start and switching only when its voltage exceeds 2.6V (rising) and disables operation below 2.5V (falling), acting as an internal power-good monitor.
How does LT8330HS6#TRMPBF achieve 6µA quiescent current?
LT8330HS6#TRMPBF achieves 6µA quiescent current in Burst Mode by completely disabling the oscillator, gate driver, and error amplifier between energy pulses-leaving only essential bias circuitry active. Output voltage is maintained by the output capacitor during these sleep periods, and the IC wakes only when VOUT droop triggers a new burst, minimizing average VIN current while keeping ripple <15mV.
