Product details
Overview
LT8330ES6#TRPBF from Analog Devices is a 6µA quiescent current, 2MHz fixed-frequency current-mode DC/DC converter with integrated 1A/60V power switch, configurable as boost, SEPIC, or inverting topology. It delivers regulated positive or negative output voltages using a single FBX pin and supports 3V–40V input for applications including portable medical diagnostics and industrial sensor power rails.
For engineers reviewing the LT8330ES6#TRPBF datasheet, LT8330ES6#TRPBF pinout, LT8330ES6#TRPBF application, or LT8330ES6#TRPBF equivalent, key selection criteria include ultralow IQ operation, ±0.8V/1.6V FBX regulation thresholds, EN/UVLO hysteresis control, internal soft-start/frequency foldback, and TSOT-23 thermal performance at 125°C junction temperature.
Technical Context
The LT8330ES6#TRPBF employs fixed-frequency (2MHz) current-mode control with dual error amplifiers-one active for positive outputs (1.6V reference), the other for negative outputs (–0.8V reference)-enabling topology selection via FBX voltage polarity. Its internal compensation eliminates external loop components.
During start-up or low-VOUT fault conditions, frequency foldback reduces switching frequency to maintain stable inductor current control when duty cycle approaches minimum on-time limits. Thermal lockout halts switching above 170°C and resumes with soft-start after die cooling by 5°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Quiescent Current | 6µA in Burst Mode - enables >10-year battery life in always-on IoT sensors |
| Switch Rating | 1A continuous, 60V max - supports 48V boost and –48V inverting rails without external FET |
| FBX Regulation | 1.6V (positive VOUT) or –0.8V (negative VOUT) - single feedback pin simplifies layout across topologies |
| EN/UVLO Threshold | 1.68V rising / 1.60V falling with 80mV hysteresis - precise system-level input voltage sequencing |
| Switching Frequency | Fixed 2MHz - allows use of sub-1µH inductors and compact ceramic output capacitors |

| Package | 6-Lead TSOT-23 (0.95mm height) - low-profile footprint compatible with dense PCB layouts |
Pinout & Package
LT8330ES6#TRPBF uses a 6-lead plastic TSOT-23 package (0.95mm max height, 2.9mm × 1.6mm footprint) with θJA = 125°C/W. Exposed pad not present; GND (Pin 2) must connect to PCB ground plane for thermal and noise integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 3V–40V; requires local 4.7µF ceramic bypass placed adjacent to pin |
| INTVCC | Internally regulated 3V supply | Powers internal logic/gate driver; must be bypassed with ≥1µF low-ESR ceramic to GND |
| EN/UVLO | Enable and undervoltage lockout input | Logic-controlled shutdown; 1.6V threshold enables precise input voltage sequencing |
| SW | Drain of internal 60V/1A power switch | Connects to inductor/diode node; minimize trace area to reduce EMI radiation |
| GND | Power and signal reference | Primary thermal path; tie Pin 2 directly to large copper ground plane |
| FBX | Feedback regulation input | Dual-reference pin: 1.6V for positive VOUT, –0.8V for negative VOUT; sets output via resistor divider |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT8331ES6#TRPBF | Higher 2.5A switch current, same 60V rating and 2MHz frequency; adds programmable spread-spectrum modulation | Better suited for higher-power loads (>500mA) and EMI-sensitive RF subsystems | Select LT8331ES6#TRPBF when output current exceeds 1A or spread-spectrum EMI reduction is required |
| TPS61088RHLR | 12V max switch rating, 3.5A switch, 2.5V–12V input range; no inverting/SEPIC support | Limited to boost-only operation up to +15V; unsuitable for negative rail generation or 40V input | Choose TPS61088RHLR only for low-voltage, high-current boost applications where topology flexibility is unnecessary |
Compared with LT8330ES6#TRPBF, LT8331ES6#TRPBF offers higher current capability and EMI mitigation but increases solution size and cost; TPS61088RHLR provides higher peak current at lower voltage but lacks the critical topology versatility and ultralow IQ needed for battery-powered or wide-input industrial designs.

FAQ
What is the maximum input voltage supported by the LT8330ES6#TRPBF?
The LT8330ES6#TRPBF supports an absolute maximum input voltage of 40V on the VIN pin. Its operational input range is specified from 3V to 40V, making it suitable for 24V industrial buses, 12V automotive systems, and wide-range battery-powered equipment. Exceeding 40V risks permanent damage per Absolute Maximum Ratings.
Can the LT8330ES6#TRPBF generate a negative output voltage?
Yes, the LT8330ES6#TRPBF can generate a regulated negative output voltage using its inverting topology configuration. When the FBX pin is pulled below GND to –0.8V via a resistor divider, the internal amplifier A2 activates to regulate negative VOUT. This eliminates need for external inverter ICs in bipolar supply designs.
How does the LT8330ES6#TRPBF achieve 6µA quiescent current?
The LT8330ES6#TRPBF achieves 6µA quiescent current through low-ripple Burst Mode operation: during light loads, it delivers discrete current pulses to the output capacitor, then enters deep sleep where most internal circuitry is disabled. This architecture maintains regulation while minimizing VIN current draw - critical for battery longevity.
Is the LT8330ES6#TRPBF pin-compatible with other members of the LT8330 family?
No, the LT8330ES6#TRPBF is not pin-compatible with DFN-packaged variants (e.g., LT8330EDDB#TRPBF) due to differing pin counts (6 vs. 8) and layouts. However, all LT8330 variants share identical functional pin definitions and electrical behavior - only mechanical interface and thermal performance differ between TSOT-23 and DFN packages.
What protection features are integrated into the LT8330ES6#TRPBF?
The LT8330ES6#TRPBF integrates frequency foldback during start-up or low-output faults, thermal lockout at 170°C (with automatic soft-start recovery after 5°C cooldown), and accurate EN/UVLO with 80mV hysteresis. It does not include overcurrent latch-off or short-circuit foldback - external current limiting is recommended for sustained overload conditions.
