Product details
Overview
LTC3410ESC6-1.8#TRMPBF from Analog Devices (formerly Linear Technology) is a fixed-output, high-efficiency synchronous step-down DC/DC regulator delivering 1.8V at up to 300mA from a 2.5V–5.5V input. It features 2.25MHz constant-frequency operation, 96% peak efficiency, ±2% output voltage accuracy, and operates in Burst Mode with 26µA quiescent current-optimized for Li-ion-powered portable instrumentation.
For engineers reviewing the LTC3410ESC6-1.8#TRMPBF datasheet, LTC3410ESC6-1.8#TRMPBF pinout, LTC3410ESC6-1.8#TRMPBF application, or LTC3410ESC6-1.8#TRMPBF equivalent, key selection criteria include its SC70-6 package footprint, 1.8V fixed output with no external feedback resistors, low-noise Burst Mode performance below 10mA load, and compatibility with ceramic input/output capacitors without ESR requirements.
Technical Context
The LTC3410ESC6-1.8#TRMPBF implements a constant-frequency, current-mode synchronous buck architecture with integrated P-channel main and N-channel synchronous switches. Its 2.25MHz switching frequency enables compact 2.2–4.7µH inductor and 4.7µF ceramic capacitor designs, while slope-compensated control ensures stability across all duty cycles-including 100% dropout operation.
Burst Mode operation reduces quiescent current to 26µA by intermittently enabling switching cycles only as needed to maintain regulation, with automatic transition to PWM mode above ~10mA load. Overtemperature protection disables both switches when junction temperature exceeds ~150°C, and undervoltage lockout engages below 1.94V (falling) or 2.3V (rising).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±2% at 100mA load-eliminates external feedback divider and simplifies layout. |
| Max Output Current | 300mA continuous-supports moderate-power digital loads like microcontrollers and sensors in portable systems. |
| Input Voltage Range | 2.5V to 5.5V-fully covers single-cell Li-ion (2.7V–4.2V) and regulated 3.3V/5V rails. |
| Switching Frequency | 2.25MHz (typ.)-enables use of sub-5mm surface-mount inductors and minimizes PCB area. |
| Quiescent Current | 26µA in Burst Mode-extends battery runtime in standby or low-duty-cycle applications. |
| Efficiency | Up to 96% at 100mA, VIN = 3.6V-reduces thermal load and improves power budget in space-constrained designs. |
| Shutdown Current | <1µA-enables deep-sleep system states without significant leakage drain. |
| Package | 6-lead SC70 (2.0mm × 1.25mm × 0.9mm)-low-profile, thermally enhanced plastic package compatible with standard reflow. |
Pinout & Package
Supplied in a 6-lead SC70 plastic package (2.0mm × 1.25mm × 0.9mm), the LTC3410ESC6-1.8#TRMPBF uses a standardized pinout optimized for minimal loop area and thermal performance. All pins are surface-mount compatible with standard lead-free reflow profiles.
| 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-must not be left floating. |
| GND (Pins 2, 5) | Power and signal ground reference | Dual ground pins reduce ground impedance and improve noise immunity; both must connect to low-impedance PCB ground plane. |
| SW (Pin 3) | Switch node connection | Connects to inductor and internal P/N MOSFET drains-requires short, wide trace to minimize EMI and switching losses. |
| VIN (Pin 4) | Main input supply | Accepts 2.5V–5.5V input; requires local 4.7µF ceramic decoupling placed adjacent to pin for high-frequency current return. |
| VOUT (Pin 6) | Fixed-output feedback node | Internally connected to 1.8V reference divider-no external resistors needed; connects directly to output capacitor positive terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Eliminates external Schottky diode-reduces conduction loss and improves efficiency across full load range. |
| Ceramic capacitor stability | No ESR dependency-enables use of low-ESR, high-ripple-current X5R/X7R ceramics for ultra-low output ripple and small footprint. |
| 100% duty cycle operation | Supports dropout down to VIN ≈ VOUT + ILOAD × RDS(ON)-extends usable battery life in Li-ion systems nearing end-of-discharge. |
| Burst Mode low-noise regulation | 20mVP-P output ripple at light loads-meets noise-sensitive analog and RF circuit requirements without additional filtering. |
| Integrated overtemperature protection | Thermal shutdown at ~150°C junction-prevents damage during sustained overload or poor heatsinking conditions. |
| Low-input-voltage UVLO | 2.3V turn-on / 1.94V turn-off thresholds-prevents erratic startup or brownout operation near battery cutoff. |

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 | 1.8V fixed, 300mA, 3MHz, 17µA IQ-but requires external compensation and lacks 100% duty cycle. | Better light-load efficiency but higher design complexity; unsuitable for true dropout scenarios. | Select if highest efficiency >1mA load is critical and layout allows compensation network. |
| MAX17532ATA+ | Adjustable 0.8–5V, 400mA, 2.2MHz, 25µA IQ-wider VIN (4.5–36V), larger 10-pin TDFN package. | Designed for industrial input ranges; overqualified for single-cell Li-ion; higher cost and footprint. | Select only if future voltage flexibility or higher input range is required-adds unnecessary overhead for 1.8V Li-ion use. |

FAQ
What is the maximum continuous output current of the LTC3410ESC6-1.8#TRMPBF?
The LTC3410ESC6-1.8#TRMPBF delivers up to 300mA continuous output current at ambient temperatures ≤85°C with adequate PCB copper area for heat dissipation. Peak inductor current capability is 380mA minimum, supporting transient loads typical in microcontroller and sensor applications. Derating is recommended above 70°C ambient or under high-duty-cycle dropout conditions.
Does the LTC3410ESC6-1.8#TRMPBF require external feedback resistors?
No. The LTC3410ESC6-1.8#TRMPBF is a fixed-output variant with an internal resistive divider set to 1.8V. Pin 6 is labeled VOUT-not VFB-and connects directly to the output capacitor. No external resistors are needed, reducing component count and layout sensitivity compared to adjustable versions.
Can the LTC3410ESC6-1.8#TRMPBF operate with input voltage equal to the output voltage?
Yes. The LTC3410ESC6-1.8#TRMPBF supports 100% duty cycle operation, allowing regulation down to VIN ≈ VOUT + ILOAD × RDS(ON). At 300mA and 70°C junction temperature, RDS(ON) of the P-channel switch is ~1.0Ω, enabling functional operation down to ~2.1V input-critical for maximizing Li-ion battery utilization.
What ceramic capacitor dielectrics are recommended for the LTC3410ESC6-1.8#TRMPBF?
X5R and X7R dielectrics are explicitly recommended for both input (CIN) and output (COUT) capacitors with the LTC3410ESC6-1.8#TRMPBF. These offer superior voltage coefficient and temperature stability versus Y5V/Z5U, ensuring consistent 4.7µF capacitance across operating conditions and preventing output voltage drift or instability.
How does Burst Mode operation affect output voltage ripple in the LTC3410ESC6-1.8#TRMPBF?
In Burst Mode, the LTC3410ESC6-1.8#TRMPBF maintains low output voltage ripple-typically 20mVP-P-by regulating each burst event tightly and minimizing sleep-state droop. Unlike conventional PFM regulators, its controlled burst timing and synchronous rectification prevent large low-frequency ripple components, preserving signal integrity for noise-sensitive analog circuits.
