Product details
Overview
LT8410EDC-1#TRMPBF from Analog Devices (formerly Linear Technology) is an ultralow-power boost converter IC with integrated NPN switch, Schottky diode, and PMOS output disconnect. It delivers up to 40V output from 2.5V–16V input, features 8.5μA quiescent current, 8mA switch current limit, and operates in a 2mm × 2mm 8-pin DFN package. It is used in RF MEMS relay power supplies where low standby power and output isolation during shutdown are critical.
For engineers reviewing the LT8410EDC-1#TRMPBF datasheet, LT8410EDC-1#TRMPBF pinout, LT8410EDC-1#TRMPBF application, or LT8410EDC-1#TRMPBF equivalent, key selection criteria include its 8mA switch current limit (vs. 25mA in LT8410), 4mA PMOS disconnect current limit, integrated high-value feedback resistors (12.4MΩ/0.4MΩ), soft-start via VREF capacitor, and overvoltage protection on CAP and VOUT pins.
Technical Context
The LT8410EDC-1#TRMPBF employs a variable peak inductor current and variable off-time control scheme to maintain high efficiency across wide load ranges while minimizing output voltage ripple. Its internal 1.235V reference and FBP-based feedback enable precise output voltage setting up to 40V using external resistor dividers or direct biasing.
It integrates a comparator on the SHDN pin with 1.30V turn-on threshold and 60mV hysteresis, enabling programmable enable functionality. The PMOS output disconnect blocks VOUT from VIN during shutdown, limiting reverse current to ≤4mA and ensuring true output isolation - essential for sensor bias and RF MEMS applications requiring zero-load leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 16V - supports single-cell Li-ion, multi-cell alkaline, and industrial 12V rails without pre-regulation. |
| Output Voltage Range | Up to 40V - enables biasing of high-voltage RF MEMS switches and precision sensors. |
| Switch Current Limit | 8mA (typ.) - lower than LT8410's 25mA; optimized for low-power, low-output-current applications. |
| Quiescent Current | 8.5μA (active), 0μA (shutdown) - minimizes battery drain in always-on sensor nodes. |
| Reference Voltage | 1.235V (±15mV) - stable internal bandgap reference used to set output via FBP divider ratio of 31.85. |
| Package | 8-pin 2mm × 2mm DFN with exposed pad - compact footprint ideal for space-constrained portable and IoT designs. |
| Shutdown Threshold | SHDN pin < 0.3V disables device; >1.45V enables - compatible with standard logic-level GPIOs. |
Pinout & Package
LT8410EDC-1#TRMPBF is housed in an 8-pin plastic DFN (DC8) package measuring 2mm × 2mm with an exposed thermal pad (Pin 9, GND). The package requires soldering of the exposed pad to PCB ground for thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SHDN (Pin 1) | Enable/disable control input | Internal comparator with 1.30V threshold and 60mV hysteresis; must not be left floating. |
| VCC (Pin 2) | Main input supply | Accepts 2.5V–16V; requires local 2.2μF ceramic bypass capacitor to GND. |
| GND (Pin 3) | Power and signal reference | Primary ground connection; tie directly to low-impedance PCB ground plane. |
| SW (Pin 4) | Switch node | Collector of internal NPN power switch; high dV/dt node - minimize trace area to reduce EMI. |
| VOUT (Pin 5) | Regulated output (post-disconnect) | Drain of internal PMOS disconnect switch; connect 0.1–1μF ceramic capacitor to GND for stability. |
| CAP (Pin 6) | Boost capacitor node | Cathode of internal Schottky diode; place 0.1–1μF capacitor to GND to filter inductor current ripple. |
| VREF (Pin 7) | 1.235V reference output | Provides stable reference for FBP divider; optional 47–220nF capacitor enables soft-start ramp control. |
| FBP (Pin 8) | Feedback positive input | Sets output voltage via VOUT = 31.85 × VFBP; bias with resistor divider from VREF or external reference. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow quiescent current | 8.5μA active / 0μA shutdown - extends battery life in energy-harvesting and remote sensor systems. |
| Integrated output disconnect | PMOS switch isolates VOUT from VIN during shutdown, limiting reverse current to ≤4mA and preventing load backfeed. |
| High-value on-chip feedback resistors | 12.4MΩ/0.4MΩ divider reduces input-referred quiescent current and eliminates two external components. |
| Programmable enable with hysteresis | SHDN pin comparator allows user-defined turn-on/off thresholds using external resistor networks (e.g., Figure 2). |
| Overvoltage protection | Hardware clamping limits CAP and VOUT pins to ≤40V - protects internal circuitry during fault or startup transients. |
| Soft-start via VREF capacitor | 70μs discharge + 10μA charge cycle controls VREF ramp rate, reducing inrush current and peak inductor stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT8410EDC#TRMPBF | 25mA switch current limit, 19mA PMOS disconnect limit, higher output current capability. | Better suited for loads >1mA; less suitable where ultra-low IQ and minimal shutdown leakage are mandatory. | Select when higher output power is needed and 8.5μA IQ remains acceptable - same pinout and footprint. |
| LT3464EDD#TRMPBF | 2.3–10V input, 34V max output, 85mA switch limit, 25μA IQ, no integrated output disconnect. | Lacks PMOS disconnect; requires external MOSFET for output isolation; higher IQ reduces battery life. | Choose only if wider switching frequency range (1.2MHz) or higher output current is prioritized over shutdown isolation and ultralow IQ. |
Compared with LT8410EDC#TRMPBF, the LT8410EDC-1#TRMPBF trades peak output current for lower quiescent consumption and tighter shutdown isolation - making it optimal for micro-power sensor and RF MEMS biasing. Compared with LT3464EDD#TRMPBF, it offers true output disconnect and 3× lower IQ, but narrower input voltage range and no high-frequency option.

FAQ
What is the maximum output voltage supported by the LT8410EDC-1#TRMPBF?
The LT8410EDC-1#TRMPBF supports a maximum output voltage of 40V, enforced by internal overvoltage protection on the CAP and VOUT pins. Even if the FBP pin voltage is driven above the reference, the output will clamp at 40V - ensuring safe operation for RF MEMS and high-voltage sensor biasing applications.
How does the LT8410EDC-1#TRMPBF differ from the LT8410EDC#TRMPBF?
The LT8410EDC-1#TRMPBF has an 8mA switch current limit and 4mA PMOS disconnect current limit, versus 25mA and 19mA in the LT8410EDC#TRMPBF. This makes the -1 variant optimized for lower-power applications where strict IQ and shutdown isolation outweigh raw output current capability - both share identical pinout, package, and feature set.
Can the LT8410EDC-1#TRMPBF be used without an external FBP resistor divider?
Yes - the LT8410EDC-1#TRMPBF allows direct biasing of the FBP pin using an external reference or DAC output, enabling dynamic output voltage control. However, the internal 12.4MΩ/0.4MΩ feedback divider remains active; for full flexibility and to avoid loading effects, use a high-impedance source (>1MΩ) or disable the internal divider per design requirements.
What is the purpose of the capacitor on the VREF pin of the LT8410EDC-1#TRMPBF?
A capacitor (47–220nF) on the VREF pin of the LT8410EDC-1#TRMPBF implements soft-start: the IC discharges it for ~70μs at startup, then charges it with a 10μA current source to 1.235V. This ramps the reference voltage, slowing the rise of VOUT and limiting inrush current and peak inductor stress - critical for reliable capacitor charging and sensitive load interfaces.
Does the LT8410EDC-1#TRMPBF require special PCB layout considerations?
Yes - due to its high-efficiency, high-frequency operation, the LT8410EDC-1#TRMPBF demands careful layout: minimize SW trace length/area, return all capacitor grounds directly to the IC's GND pin, place the exposed pad solidly to PCB ground, and keep FBP/VREF traces short and shielded from noisy nodes. These practices reduce EMI and ensure stable regulation per Figure 3 in the datasheet.
