Product details
Overview
LTC3400ES6-1#TRMPBF from Analog Devices (formerly Linear Technology) is a micropower synchronous boost DC/DC converter in a 6-lead SOT-23 package, delivering up to 100mA at 3.3V from a single AA cell (0.85V start-up), featuring 1.2MHz fixed-frequency PWM, internal NMOS/PMOS switches, and automatic Burst Mode operation for ultra-low-light-load efficiency.
For engineers reviewing the LTC3400ES6-1#TRMPBF datasheet, LTC3400ES6-1#TRMPBF pinout, LTC3400ES6-1#TRMPBF application, or LTC3400ES6-1#TRMPBF equivalent, key selection criteria include minimum start-up voltage (0.85V), feedback reference (1.23V), quiescent current in Burst Mode (19µA), antiringing control for EMI reduction, and compatibility with ceramic output capacitors and low-profile inductors.
Technical Context
The LTC3400ES6-1#TRMPBF implements current-mode PWM control with internal slope compensation and a transconductance error amplifier (gm = 33 µS). Its 1.2MHz oscillator enables use of compact 4.7µH inductors and ceramic capacitors, while zero-current detection disables the synchronous rectifier at ~20mA to prevent reverse inductor current.
Burst Mode operation-exclusive to the LTC3400 variant (not LTC3400B)-shuts down non-essential circuitry below ~3mA load, reducing output quiescent current to 19µA; regulation resumes when VOUT droops ~1%, enabling extended battery life in standby without low-frequency ripple.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Start-Up Voltage | 0.85V min - enables operation from deeply discharged alkaline cells before conventional converters fail. |
| Switching Frequency | 1.2MHz typ - allows use of sub-5µH inductors and 4.7µF ceramic capacitors, minimizing solution footprint. |
| Feedback Reference | 1.23V ±2.8% - sets output voltage via external resistor divider; supports 2.5V–5V adjustable range. |
| Burst Mode IQ | 19µA typ at VOUT - draws minimal current from output capacitor during light-load sleep, extending battery runtime. |
| Shutdown Current | <1µA - ensures negligible battery drain when disabled via SHDN pin. |
| Peak Switch Current | 600mA min - limits inductor peak current to maintain stability and thermal safety under transient loads. |
| Efficiency | Up to 92% - achieved at 100mA output from 1.5V input, critical for single-cell portable power rails. |
Pinout & Package
Package: 6-lead SOT-23 (ThinSOT™), 1mm height, JEDEC MO-193 compliant, footprint compatible with standard SOT-23 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (Pin 1) | Switch node | Connects to inductor; internal NMOS switch source; antiringing circuit ties SW to VIN when inductor current reaches zero. |
| GND (Pin 2) | Power and signal ground | Primary return path for inductor current and IC bias; requires low-impedance PCB connection to output capacitor negative terminal. |
| FB (Pin 3) | Feedback input | Senses resistor divider output; regulates VOUT by comparing to 1.23V internal reference; input current <1nA minimizes divider error. |
| SHDN (Pin 4) | Logic shutdown control | Active-high input; pulls internal circuitry into sub-1µA shutdown state when driven low; typically pulled up to VIN via 1MΩ resistor. |
| VOUT (Pin 5) | Output voltage sense / rectifier drain | Drain of internal PMOS synchronous rectifier; supplies bias once VOUT > VIN; body diode holds VOUT ≈ VIN – 0.6V in shutdown. |
| VIN (Pin 6) | Battery input | Start-up bias source; after startup, device operates independently of VIN as long as output power demand is met. |
Key Features
| Feature | Design Value |
|---|---|
| Internal synchronous rectification | Eliminates external Schottky diode losses; enables >92% efficiency at 100mA with only NMOS/PMOS on-chip switches. |
| Antiringing control | Damps SW-node LC resonance at discontinuous conduction, reducing high-frequency EMI without snubbers or layout compromises. |
| Low-voltage start-up | Operates from 0.85V input - supports full functionality even as alkaline cells deplete below 1.0V. |
| Burst Mode optimization | Reduces output quiescent current to 19µA while maintaining tight regulation; ideal for intermittent-load applications like GPS receivers and pagers. |
| Tiny external component count | Requires only one inductor, two ceramic capacitors, and two resistors - no compensation network or external MOSFETs needed. |
Applications
| GPS Receivers | Handheld Instruments |
|---|---|
Use Scenario: Portable GPS units powered by single AA/AAA batteries requiring stable 3.3V rail for RF front-end and baseband ICs during intermittent satellite acquisition.

IC Role / Device Role / Timing Role: Configurable boost stage (via FB divider) generating precise 2.5V or 3.3V outputs; supports fast load transients during auto-focus and flash charging. Use Value: 600mA peak current limit handles flash capacitor charge surges; 1.2MHz frequency enables small 3.3µH inductor for space-constrained camera modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC3400ES6#TRMPBF | Same die, identical Burst Mode behavior and pinout; differs only in output voltage preset (3.3V fixed vs. adjustable via FB). | Fixed 3.3V output eliminates need for FB resistors; simplifies BOM and layout for standard logic rails. | Select when 3.3V is required and design simplicity is prioritized over adjustability. |
| LTC3400BES6-1#TRMPBF | No Burst Mode; continuous switching at light loads; higher light-load IQ (~300µA active vs. 19µA Burst Mode). | Eliminates low-frequency output ripple but sacrifices battery life in standby; preferred where ripple-sensitive analog circuits are present. | Select when consistent 1.2MHz switching is mandatory and light-load efficiency is secondary to ripple performance. |
Compared with LTC3400ES6#TRMPBF, the LTC3400ES6-1#TRMPBF offers identical functionality with factory-set 3.3V output, reducing external components; versus LTC3400BES6-1#TRMPBF, it trades continuous light-load operation for superior standby efficiency via Burst Mode-critical for infrequently active portable devices.

FAQ
What is the minimum input voltage required for the LTC3400ES6-1#TRMPBF to start switching?
The LTC3400ES6-1#TRMPBF has a guaranteed minimum start-up voltage of 0.85V at 1mA load. It will begin switching and regulate 3.3V output from a single AA cell even as the battery discharges below 1.0V, making it suitable for deep-discharge portable applications where other boost converters fail to initiate.
Does the LTC3400ES6-1#TRMPBF require external compensation components?
No, the LTC3400ES6-1#TRMPBF uses an internally compensated current-mode PWM architecture. No external compensation network is needed-only an inductor, input/output capacitors, and optional FB resistors (though not required for the fixed 3.3V LTC3400ES6-1#TRMPBF variant) are necessary for full operation.
How does Burst Mode operation improve battery life in the LTC3400ES6-1#TRMPBF?
Burst Mode reduces the LTC3400ES6-1#TRMPBF's quiescent current to 19µA at VOUT during light loads (<3mA), drastically lowering average battery drain. The device cycles between brief PWM bursts and deep sleep, maintaining regulation while extending standby time in devices like pagers and GPS receivers far beyond continuous-switching alternatives.
Can the LTC3400ES6-1#TRMPBF drive a 100mA load continuously from a 1.2V input?
Yes-the LTC3400ES6-1#TRMPBF delivers 100mA at 3.3V from a 1.2V input with up to 92% efficiency, as verified in Figure 1 and Typical Performance data. This capability relies on its low RDS(ON) NMOS (0.35Ω) and PMOS (0.45Ω) switches and optimized 1.2MHz current-mode control.
What package type and dimensions does the LTC3400ES6-1#TRMPBF use?
The LTC3400ES6-1#TRMPBF is housed in a 6-lead SOT-23 (ThinSOT™) package measuring 2.90mm × 1.60mm × 1.00mm max height. It complies with JEDEC MO-193 and uses standard SOT-23 solder pad geometry per IPC-7351, enabling drop-in replacement in existing layouts.
