Product details
Overview
LT8330ES6#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. It delivers ultralow 6µA quiescent current in Burst Mode, supports ±40V input range, and generates positive or negative regulated outputs using a single FBX pin - ideal for space-constrained industrial sensors and portable medical diagnostics requiring high light-load efficiency.
For engineers reviewing the LT8330ES6#TRMPBF datasheet, LT8330ES6#TRMPBF pinout, LT8330ES6#TRMPBF application, or LT8330ES6#TRMPBF equivalent, key selection criteria include its 2MHz fixed switching frequency, 1.6V EN/UVLO threshold with 80mV hysteresis, internal compensation, soft-start, and TSOT-23-6 package thermal performance at –40°C to 125°C junction temperature.
Technical Context
The LT8330ES6#TRMPBF employs fixed-frequency (2MHz) current-mode control with dual error amplifiers enabling topology-agnostic regulation: A1 active for positive output (FBX referenced to +1.6V), A2 active for negative output (FBX referenced to –0.8V). Its frequency foldback activates when FBX approaches GND during startup or fault, extending off-time to prevent inductor current runaway.
Internal soft-start ramps the VC node to limit peak inductor current during startup; thermal lockout disables switching above 170°C with automatic soft-start recovery. The INTVCC LDO supplies 3V internally, requiring ≥1µF ceramic bypassing, and cannot be externally loaded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3V to 40V - supports wide industrial and automotive battery inputs without external pre-regulation. |
| Quiescent Current (Burst Mode) | 6µA - enables multi-year battery life in always-on IoT sensors and portable diagnostic devices. |
| Switch Rating | 1A, 60V - handles 48V boost conversion (e.g., 12V→48V @135mA) with margin for transient overvoltage. |
| Switching Frequency | Fixed 2MHz - permits use of sub-1µH inductors (e.g., 6.8µH) for minimal PCB footprint and EMI filtering. |
| FBX Regulation Voltage | +1.60V (positive VOUT) or –0.80V (negative VOUT) - single-pin topology selection eliminates external mode-switching logic. |
| EN/UVLO Threshold | 1.68V rising / 1.60V falling with 80mV hysteresis - enables precise, stable input undervoltage lockout for system brownout protection. |
| Package | TSOT-23-6 (0.95mm height) - low-profile, thermally enhanced package with θJA = 125°C/W for convection-cooled designs. |
Pinout & Package
LT8330ES6#TRMPBF uses the 6-lead Plastic TSOT-23 package (0.95mm max height), optimized for thermal dissipation in space-constrained applications. Pin 2 (GND) must connect to a solid ground plane; VIN and SW traces require minimized loop area to suppress EMI.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Supply Connection | Accepts 3–40V; requires local 4.7µF ceramic bypass capacitor placed adjacent to pin for ripple suppression and EMI reduction. |
| INTVCC | Internally Regulated 3V Supply | Powers internal circuitry; 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 via resistor divider; draws <1µA when pulled below 0.2V. |
| SW | Internal Power Switch Drain | Connects to inductor/diode node; trace must be short and wide to minimize parasitic inductance and voltage spikes. |
| GND | Power and Signal Ground Reference | Primary return path; connects to PCB ground plane to ensure stable regulation and thermal conduction. |
| FBX | Topology-Agnostic Feedback Input | Sets output voltage polarity and magnitude: +1.6V reference for boost/SEPIC, –0.8V for inverting configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow Quiescent Current | 6µA in Burst Mode maintains >85% efficiency at 1mA load - critical for battery-powered field instruments. |
| Single-Pin Topology Selection | FBX pin automatically configures error amplifier (A1 or A2) based on output polarity - eliminates external configuration pins or jumpers. |
| Integrated Soft-Start | 1ms controlled VC ramp limits inrush current during startup - prevents inductor saturation and protects downstream loads. |
| Frequency Foldback Protection | Reduces switching frequency when FBX nears GND - ensures stable control during startup or output short-circuit recovery. |
| Thermal Lockout with Auto-Recovery | Halts switching at 170°C junction temperature and resumes with soft-start after 5°C cooldown - prevents permanent thermal damage. |
Applications
| Industrial Sensor Transmitters | Portable Medical Diagnostics |

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 (3×2mm), AEC-Q100 qualified, higher thermal performance (θJA = 60°C/W), same electrical specs. | Better suited for automotive under-hood applications requiring extended temperature operation and lower thermal resistance. | Select LT8331EDDB#TRMPBF when board layout allows larger package and thermal management demands exceed TSOT-23 capability. |
| TPS61088RHLR | 5.5V max input, 12V max SW, 1.2A switch, 2.5MHz switching, no inverting/SEPIC support, different feedback architecture. | Limited to boost-only operation up to 12V output; unsuitable for negative rails or 48V boost applications. | Choose TPS61088RHLR only for low-voltage (<12V) boost applications where cost sensitivity outweighs topology flexibility. |
Compared with LT8330ES6#TRMPBF, LT8331EDDB#TRMPBF offers superior thermal handling in automotive environments but requires PCB redesign, while TPS61088RHLR sacrifices topology versatility and voltage range for lower unit cost in non-critical consumer boost applications.

FAQ
What is the maximum input voltage supported by the LT8330ES6#TRMPBF?
The LT8330ES6#TRMPBF supports an input voltage range of 3V to 40V, with absolute maximum ratings specifying VIN and EN/UVLO pins up to 40V. Exceeding 40V risks permanent damage per Absolute Maximum Ratings. For systems with potential transients (e.g., automotive load dump), external clamping or pre-regulation is required before the LT8330ES6#TRMPBF input.
Can the LT8330ES6#TRMPBF generate a negative output voltage?
Yes, the LT8330ES6#TRMPBF can generate a negative output voltage when configured as an inverting converter. This is achieved by connecting the FBX pin to a resistor divider between VOUT and GND, referencing FBX to the internal –0.80V threshold. The block diagram confirms amplifier A2 activation in this mode, enabling stable regulation without additional components.
What is the purpose of the INTVCC pin on the LT8330ES6#TRMPBF?
The INTVCC pin on the LT8330ES6#TRMPBF provides a regulated 3V supply for internal circuitry, derived from VIN via an integrated LDO. It must be bypassed with ≥1µF low-ESR ceramic capacitor to GND and cannot be externally loaded or driven - doing so violates Absolute Maximum Ratings and may cause malfunction or damage to the LT8330ES6#TRMPBF.
How does the LT8330ES6#TRMPBF achieve 6µA quiescent current?
The LT8330ES6#TRMPBF achieves 6µA quiescent current through its proprietary low-ripple Burst Mode operation: during light loads, it delivers discrete current pulses to the output capacitor, then enters deep sleep where all switching and control circuitry is disabled. This architecture is validated in the Typical Performance Characteristics section (Figure G10/G11) and confirmed in Electrical Characteristics (VIN Quiescent Current, Sleep Mode).
Is the LT8330ES6#TRMPBF pin-compatible with other variants in the LT8330 family?
Yes, the LT8330ES6#TRMPBF shares identical pinout and footprint with all TSOT-23-6 variants (e.g., LT8330IS6#TRMPBF, LT8330JS6#TRMPBF). Differences are limited to temperature grade (E = –40°C to 125°C), packaging (TRMPBF = 500-piece tape-and-reel), and internal test screening - no PCB layout changes are needed when substituting within the S6 package family.
