Product details
Overview
LTC3410ESC6-1.2#TRMPBF from Analog Devices (formerly Linear Technology) is a monolithic synchronous step-down DC/DC regulator in SC70-6 package, delivering up to 300mA output current with 1.2V fixed output voltage, 2.25MHz switching frequency, and ±2% output voltage accuracy over –40°C to 85°C. It operates from 2.5V to 5.5V input, supports 100% duty cycle for low-dropout operation, and targets Li-ion–powered portable electronics requiring high efficiency at light loads.
For engineers reviewing the LTC3410ESC6-1.2#TRMPBF datasheet, LTC3410ESC6-1.2#TRMPBF pinout, LTC3410ESC6-1.2#TRMPBF application, or LTC3410ESC6-1.2#TRMPBF equivalent, key selection criteria include its 26µA quiescent current in Burst Mode, 96% peak efficiency, ceramic-capacitor compatibility, absence of external Schottky diode requirement, and thermal performance under dropout conditions at 300mA load.
Technical Context
The LTC3410ESC6-1.2#TRMPBF employs constant-frequency current-mode control with internal P-channel main switch (RDS(ON) = 0.75Ω typ) and N-channel synchronous switch (RDS(ON) = 0.55Ω typ), enabling stable regulation across wide input/output ratios. Its patented slope compensation maintains full 380mA peak inductor current capability even above 40% duty cycle.
Burst Mode operation reduces supply current to 26µA at light loads by intermittently enabling switching cycles while maintaining output regulation via feedback error amplifier sleep/wake thresholds; shutdown draws <1µA. Oscillator frequency is internally fixed at 2.25MHz (1.8–2.7MHz range), eliminating external timing components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±2% at 100mA load - ensures precise core voltage for low-power microcontrollers and sensors. |
| Max Output Current | 300mA continuous - sufficient for baseband processors, RF transceivers, and imaging subsystems in handheld devices. |
| Input Voltage Range | 2.5V to 5.5V - fully supports single-cell Li-ion (2.7–4.2V) with margin for USB-powered backup. |
| Switching Frequency | 2.25MHz (typ) - enables use of compact 2.2–4.7µH inductors and 4.7µF ceramic capacitors, minimizing PCB footprint. |
| Quiescent Current | 26µA in Burst Mode - extends battery runtime in standby/sleep states without compromising transient response. |
| Efficiency | Up to 96% at 100mA - minimizes thermal stress and power loss in thermally constrained SC70-6 package. |
| Duty Cycle | 100% - sustains regulation down to VIN ≈ VOUT + ILOAD × RDS(ON), critical for end-of-battery-life operation. |
| Thermal Resistance | θJA = 250°C/W - requires minimal copper area for thermal management in portable layouts. |
Pinout & Package
Package: SC70-6 (6-lead plastic SC70), 2.0mm × 1.25mm × 0.9mm profile, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable control input | Logic-high (>1.5V) enables regulation; logic-low (<0.3V) forces shutdown with <1µA supply current - used for system-level power sequencing. |
| GND (Pins 2, 5) | Power and signal ground | Dual ground pins reduce ground impedance and improve noise immunity in high-frequency switching paths. |
| SW (Pin 3) | Switch node | Connects to inductor; carries high dv/dt square wave - must be routed short and away from sensitive analog nodes (e.g., VFB). |
| VIN (Pin 4) | Main input supply | Accepts 2.5–5.5V; requires local 4.7µF ceramic decoupling capacitor to suppress high-frequency ripple and EMI. |
| VOUT (Pin 6) | Fixed-output feedback reference | Internally connected to 1.2V output divider - no external resistors needed; enables compact layout for fixed-voltage applications. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Eliminates external Schottky diode - reduces BOM count, improves efficiency by 5–10% vs. asynchronous designs, and lowers thermal dissipation. |
| Ceramic capacitor stability | No ESR dependency for loop stability - allows use of low-ESR, small-footprint X5R/X7R ceramics for both input and output, cutting board area by >30%. |
| Burst Mode operation | 26µA IQ with 20mVP-P output ripple - maintains regulation during ultra-low-power sleep modes without sacrificing transient recovery speed. |
| Low dropout operation | 100% duty cycle capability - sustains 1.2V output down to ~1.35V input (at 300mA), extending usable battery life by ~15% in Li-ion discharge curves. |
| Overtemperature protection | Thermal shutdown at ~150°C junction - prevents permanent damage during sustained overload or poor heatsinking, with automatic recovery on cooldown. |
| Internal 0.8V reference | Enables fixed 1.2V output via precision internal resistor divider - eliminates external component tolerance errors and layout sensitivity of adjustable versions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYR | 1.2V fixed, 300mA, 3MHz, 17µA IQ, 0.5mm pitch DSBGA-6 - smaller package but lower max input (5.5V same), no 100% duty cycle. | Preferred for space-constrained wearables where 3MHz allows sub-1µH inductors; unsuitable for deep-dropout Li-ion end-of-life operation. | Select TPS62231DRYR only if board area is primary constraint and input never drops below 1.5× VOUT. |
| MAX17222ELT+T | 1.2V fixed, 500mA, 2MHz, 1.6µA IQ, 0.4mm pitch WLP-6 - lower IQ but higher RDS(ON) (1.2Ω), no thermal shutdown. | Better for ultra-long-life IoT sensors; less robust under sustained 300mA load due to higher conduction loss and no overtemperature protection. | Choose MAX17222ELT+T only for sub-100mA average loads where 1.6µA IQ outweighs thermal and current limitations. |
Compared with LTC3410ESC6-1.2#TRMPBF, TPS62231DRYR offers higher frequency and smaller footprint but sacrifices dropout capability and thermal safety, while MAX17222ELT+T achieves ultra-low IQ at the cost of peak current delivery and fault protection - making LTC3410ESC6-1.2#TRMPBF the balanced choice for portable systems demanding reliability, efficiency, and battery longevity.

FAQ
What is the maximum continuous output current of the LTC3410ESC6-1.2#TRMPBF?
The LTC3410ESC6-1.2#TRMPBF delivers up to 300mA continuous output current at 1.2V when operating within its specified input voltage range (2.5V to 5.5V) and ambient temperature (–40°C to 85°C). This rating assumes proper PCB thermal design with θJA ≤ 250°C/W and adequate input/output capacitance (4.7µF ceramic each). Peak inductor current capability is 380mA, supporting transient loads beyond steady-state limits.
Does the LTC3410ESC6-1.2#TRMPBF require an external Schottky diode?
No, the LTC3410ESC6-1.2#TRMPBF does not require an external Schottky diode. It integrates both a P-channel main switch and an N-channel synchronous rectifier, enabling full synchronous rectification. This eliminates diode forward-voltage losses, improves efficiency by 5–10% across load range, and reduces thermal dissipation compared to asynchronous buck converters.
What is the quiescent current of the LTC3410ESC6-1.2#TRMPBF in Burst Mode operation?
The LTC3410ESC6-1.2#TRMPBF draws 26µA typical quiescent current in Burst Mode operation, measured at VIN = 3.6V, VOUT = 1.2V, and light load conditions. This ultra-low IQ enables extended battery life in standby and sleep modes while maintaining tight output regulation and fast wake-up response - critical for portable devices with intermittent active periods.
Can the LTC3410ESC6-1.2#TRMPBF operate with 100% duty cycle?
Yes, the LTC3410ESC6-1.2#TRMPBF supports 100% duty cycle operation, allowing it to maintain regulation as input voltage approaches the output voltage (e.g., VIN ≈ 1.35V at 300mA). In this mode, the P-channel main switch remains continuously on, and output voltage equals VIN minus ILOAD × RDS(ON). This feature extends usable battery life in single-cell Li-ion applications nearing end-of-discharge.
Is the LTC3410ESC6-1.2#TRMPBF compatible with ceramic output capacitors?
Yes, the LTC3410ESC6-1.2#TRMPBF is fully compatible with ceramic output capacitors and is specifically optimized for them. Its current-mode control architecture does not rely on capacitor ESR for loop stability, enabling use of low-ESR X5R/X7R ceramics (e.g., 4.7µF, 0805) to achieve <20mVP-P output ripple and minimal PCB footprint - unlike many older regulators requiring tantalum or aluminum electrolytics.
