Product details
Overview
LT8330JS6#TRPBF 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, fixed 2MHz switching frequency, and single-pin FBX feedback supporting ± output voltage programming - used in automotive infotainment power rails requiring ultra-low standby consumption.
For engineers reviewing the LT8330JS6#TRPBF datasheet, LT8330JS6#TRPBF pinout, LT8330JS6#TRPBF application, or LT8330JS6#TRPBF equivalent, key selection criteria include its –40°C to 150°C junction temperature rating, TSOT-23-6 package thermal performance (θJA = 125°C/W), EN/UVLO threshold accuracy (1.60V–1.745V), and low-ripple Burst Mode operation below 15mV output ripple.
Technical Context
The LT8330JS6#TRPBF implements fixed-frequency (2MHz) current-mode control with internal compensation, soft-start, and frequency foldback triggered when FBX approaches GND during startup or fault conditions. Its dual-path error amplifier architecture enables seamless topology reconfiguration - A1 active for positive outputs (1.6V reference), A2 active for negative outputs (–0.8V reference).
Thermal lockout activates at 170°C (typical), halting switching and resetting soft-start; recovery occurs after 5°C die temperature drop. INTVCC is a regulated 3V LDO (2.5V turn-off, 2.6V turn-on) requiring ≥1µF ceramic bypassing, and SW pin leakage is limited to 1µA at 60V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3V to 40V - supports wide-input industrial and automotive battery-supplied systems without pre-regulation. |
| IQ (Sleep Mode) | 6µA typical - enables >1-year battery life in always-on sensor nodes powered by coin cells or supercaps. |
| Switch Rating | 1A continuous, 60V breakdown - handles 48V boost conversion (e.g., 12V→48V @ 135mA) with margin for transients. |
| fSW | Fixed 2MHz - permits use of sub-1µH inductors (e.g., 0.68µH–6.8µH), reducing solution size and EMI filter complexity. |
| FBX Reference | 1.60V (positive VOUT) or –0.80V (negative VOUT) - enables single-resistor-divider programming of both polarities without external op-amps. |
| EN/UVLO Threshold | 1.620V–1.745V rising, 1.556V–1.644V falling - provides precise, hysteresis-controlled input undervoltage protection for 12V/24V vehicle systems. |
| Junction Temp | –40°C to +150°C - qualified for under-hood automotive applications per AEC-Q100 (J-grade) with derated lifetime above 125°C. |
Pinout & Package
LT8330JS6#TRPBF uses the 6-lead Plastic TSOT-23 package (3.0mm × 1.7mm × 1.0mm height), optimized for high-density layouts and thermal dissipation via exposed pad grounding in DFN variants - this TSOT-23 variant relies on PCB copper area for θJA = 125°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Must be bypassed with ≥4.7µF X7R/X5R ceramic capacitor placed adjacent to pin; supports 3V–40V input range. |
| INTVCC | Internally regulated 3V supply | Requires ≥1µF low-ESR ceramic capacitor to GND; no external loading permitted - powers gate driver and internal logic. |
| EN/UVLO | Enable and undervoltage lockout input | Logic-controlled shutdown or programmable UVLO using resistor divider; draws <1µA when <0.2V. |
| SW | Internal power switch drain | Connects to inductor/diode node; minimize trace area to reduce EMI; rated 60V, 1A peak. |
| GND | Power and signal ground reference | Primary return path for switch current and feedback; tie Pin 2 directly to large PCB ground plane. |
| FBX | Feedback regulation input | Single pin accepts resistor divider from VOUT; selects 1.6V (boost/SEPIC) or –0.8V (inverting) reference automatically. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ Burst Mode | 6µA sleep current with <15mV output ripple - extends battery runtime while maintaining tight regulation at microamp loads. |
| Topology Flexibility | Single FBX pin auto-configures for boost, SEPIC, or inverting operation - eliminates need for external mode-select logic or component changes. |
| Integrated Protection | Frequency foldback (prevents inductor current walk-up at low VOUT), thermal lockout (170°C), and soft-start - prevents inrush damage during cold cranking or hot-plug events. |
| AEC-Q100 Qualified | J-grade (–40°C to +150°C) qualification - meets automotive reliability requirements for engine control, ADAS sensors, and infotainment subsystems. |
| Internal Compensation | No external compensation components required - reduces BOM count and layout sensitivity for rapid design-in across input/output combinations. |
Applications
| Automotive Infotainment Power | Industrial Sensor Node Supply |

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#TRPBF | 8-lead DFN package, AEC-Q100 Grade E (–40°C to 125°C), same electrical specs but higher thermal performance (θJA = 60°C/W) due to exposed pad. | Better suited for high-power density designs where PCB real estate allows larger DFN and thermal vias are feasible. | Select when thermal headroom is constrained and 125°C max junction suffices; not drop-in due to different pinout and package. |
| TPS61088RHLR | 10V max switch voltage, 4A switch, 2.5V–12V input, no inverting capability, 1.2MHz fSW, non-AEC-Q100. | Higher current, lower input range, no negative output support - targets consumer portable power banks, not automotive or medical. | Choose only for cost-sensitive, non-automotive applications needing >1A output; requires redesign for polarity, UVLO, and thermal validation. |
Compared with LT8330JS6#TRPBF, LT8331EDDB#TRPBF offers superior thermal handling in compact layouts but lacks J-grade temperature rating, while TPS61088RHLR delivers higher current at lower voltage but omits inverting topology, automotive qualification, and ultralow IQ - making LT8330JS6#TRPBF uniquely suitable for safety-critical, wide-temp, bipolar-output systems.

FAQ
What is the maximum allowable junction temperature for LT8330JS6#TRPBF?
The LT8330JS6#TRPBF is rated for operation up to +150°C junction temperature and is AEC-Q100 qualified for automotive use. Thermal lockout engages at approximately 170°C to halt switching, resuming only after die temperature drops by ~5°C. This J-grade rating exceeds standard industrial limits and supports placement near heat-generating components in engine compartments or sealed enclosures.
Can LT8330JS6#TRPBF generate negative output voltages?
Yes, the LT8330JS6#TRPBF supports inverting converter configuration using the same FBX pin, which automatically references to –0.80V for negative output programming. A resistor divider from VOUT to GND sets the magnitude (e.g., R1 = R2 × (|VOUT|/0.80V – 1)), eliminating need for external level-shifting circuitry - confirmed in the device's block diagram and Applications Information section.
What is the purpose of the INTVCC pin on LT8330JS6#TRPBF?
The INTVCC pin on LT8330JS6#TRPBF provides a regulated 3V supply derived from VIN, powering internal gate drivers and logic. It must be bypassed with ≥1µF low-ESR ceramic capacitor to GND and cannot be loaded externally. Its 2.5V turn-off and 2.6V turn-on thresholds coordinate soft-start sequencing and ensure reliable startup under varying input conditions.
How does LT8330JS6#TRPBF achieve 6µA quiescent current?
The LT8330JS6#TRPBF achieves 6µA quiescent current through low-ripple Burst Mode operation: during light loads, it delivers brief current pulses to the output capacitor followed by extended sleep periods where most internal circuitry is disabled. This architecture maintains regulation while minimizing VIN current - verified in Electrical Characteristics (Table 1) and Typical Performance (Figure G10/G11).
Is LT8330JS6#TRPBF pin-compatible with other LT8330 variants?
No - LT8330JS6#TRPBF uses the 6-lead TSOT-23 package, while LT8330 variants in DFN packages (e.g., LT8330JDDB#TRPBF) have 8 leads and different pin assignments (including NC and exposed pad). The TSOT-23 and DFN variants share identical electrical functionality but require separate PCB layouts; no pin-to-pin compatibility exists between S6 and DDB packages.
