Product details
Overview
LTC3410BESC6-1.875#TRMPBF from Analog Devices (formerly Linear Technology) is a fixed-output, high-efficiency synchronous step-down DC/DC regulator in SC70-6 package, delivering up to 300mA at 1.875V with 2.25MHz switching frequency, ±2% output voltage accuracy, and operation from 2.5V to 5.5V input - ideal for single Li-Ion battery-powered portable instrumentation and digital cameras.
For engineers reviewing the LTC3410BESC6-1.875#TRMPBF datasheet, LTC3410BESC6-1.875#TRMPBF pinout, LTC3410BESC6-1.875#TRMPBF application, or LTC3410BESC6-1.875#TRMPBF equivalent, key selection criteria include guaranteed 1.875V ±2% output at 100mA load, 2.25MHz constant-frequency current-mode control, SC70-6 thermal resistance (θJA = 250°C/W), and shutdown current <1µA.
Technical Context
The LTC3410BESC6-1.875#TRMPBF employs a constant-frequency, current-mode architecture with internal P-channel and N-channel synchronous MOSFETs, enabling 100% duty-cycle low-dropout operation and eliminating external Schottky diodes. Its 0.8V internal reference supports precise fixed-output regulation via internal resistive divider.
It features pulse-skipping mode at light loads for low-noise operation, overtemperature protection tripping near 125°C junction temperature, and stable ceramic capacitor compatibility without ESR dependency - all within a thermally constrained SC70-6 footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.875V ±2% at 100mA load - ensures stable core voltage for low-power microcontrollers and image sensors. |
| Input Voltage Range | 2.5V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V) and regulated 3.3V/5V rails. |
| Switching Frequency | 2.25MHz (typ), 1.8–2.7MHz (min–max) - enables use of compact 2.2–4.7µH inductors and minimizes PCB area. |
| Max Output Current | 300mA continuous - sufficient for DSPs, RF transceivers, and camera modules in portable devices. |
| Efficiency | Up to 96% at VIN=3.6V, VOUT=1.875V, IOUT=250mA - reduces thermal load and extends battery runtime. |
| Shutdown Current | <1µA - preserves battery life during system sleep modes without external enable circuitry. |
| Thermal Resistance | θJA = 250°C/W (SC70-6) - requires minimal copper pour for ≤125°C junction limit at 300mA in dropout. |
Pinout & Package
Package: 6-lead plastic SC70 (SC6), 1.80–2.20mm × 1.15–1.35mm × 0.80–1.00mm height, θJA = 250°C/W, lead-free (Pb-free) and 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 - must not be left floating. |
| GND (Pins 2, 5) | Power and signal ground | Dual ground pins reduce ground impedance and improve noise immunity; both must connect to low-impedance PCB ground plane. |
| SW (Pin 3) | Switch node | Connects to inductor and internal P/N-MOSFET drains - high dv/dt node requiring short, direct trace routing away from sensitive analog nodes. |
| VIN (Pin 4) | Main power input | Accepts 2.5–5.5V input; requires local 2.2µF ceramic decoupling capacitor placed adjacent to pin for high-frequency current return. |
| VOUT (Pin 6) | Fixed-output feedback | Internally connected to 1.875V output via precision divider - no external resistor network required; used for remote sensing in layout-critical applications. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Eliminates external Schottky diode, increasing efficiency by ~5–8% vs asynchronous designs and reducing thermal stress on PCB. |
| 100% duty cycle operation | Enables ultra-low dropout - maintains regulation down to VIN ≈ VOUT + ILOAD×RDS(ON), extending usable battery range in portable systems. |
| Ceramic capacitor stability | No ESR requirement for COUT - allows use of small, low-ESR X5R/X7R ceramics (e.g., 2.2µF) to achieve <10mVpp ripple and minimize board space. |
| Pulse-skipping mode | Maintains tight output regulation at light loads (e.g., standby) while suppressing switching noise - critical for audio and RF-sensitive subsystems. |
| Overtemperature protection | Thermal shutdown activates near 125°C junction temperature and auto-recovers upon cooling - prevents permanent damage during transient overload or poor heatsinking. |

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 | Fixed 1.8V output, 3MHz switching, 400mA IOUT, 1.8–6.5V input - higher frequency but 0.025V lower nominal output. | Requires output voltage adjustment via external resistor if 1.875V exact is mandatory; better suited for 1.8V logic rails. | Select when higher switching frequency and marginally higher current capability are prioritized over exact 1.875V match. |
| MAX17222ELT+T | Fixed 1.85V output, 2MHz switching, 300mA IOUT, 2.0–5.5V input - tighter ±1.5% accuracy but no RUN pin; always-on operation. | Lacks enable/shutdown control, limiting use in battery-powered systems requiring deep-sleep modes. | Select only for always-on applications where shutdown current <1µA is not required and 1.85V vs 1.875V offset is acceptable. |

FAQ
What is the guaranteed output voltage tolerance for LTC3410BESC6-1.875#TRMPBF across temperature and load?
The LTC3410BESC6-1.875#TRMPBF guarantees ±2% output voltage accuracy over the full –40°C to 85°C operating temperature range and for load currents from 50mA to 250mA, as specified in the Electrical Characteristics table under VOUT parameter for the -1.875 variant. This includes line, load, and temperature effects combined.
Does LTC3410BESC6-1.875#TRMPBF require external feedback resistors?
No, LTC3410BESC6-1.875#TRMPBF does not require external feedback resistors. It is a fixed-output version with an internal precision resistive divider connecting Pin 6 (VOUT) to the 0.8V reference, delivering exactly 1.875V at the output pin. External resistors are only needed for adjustable versions like LTC3410BE.
What is the maximum recommended PCB copper area for thermal relief with LTC3410BESC6-1.875#TRMPBF in SC70-6 package?
While the SC70-6 package has no thermal pad, the recommended approach for LTC3410BESC6-1.875#TRMPBF is to maximize copper area connected to Pins 2 and 5 (GND) using multiple vias to inner-layer ground planes. For 300mA continuous operation at 70°C ambient, ≥100mm² total GND copper (including inner layers) typically keeps junction temperature below 125°C given θJA = 250°C/W.
Can LTC3410BESC6-1.875#TRMPBF operate with input voltage below 2.5V?
No - the absolute minimum input voltage for functional operation of LTC3410BESC6-1.875#TRMPBF is 2.5V per the Electrical Characteristics table. Input voltage below 2.5V may cause undervoltage lockout (UVLO threshold: 1.94–2.3V falling/rising), disabling regulation. Operation below 2.5V is outside specification and not guaranteed.
Is LTC3410BESC6-1.875#TRMPBF pin-compatible with other variants in the LTC3410BESC6 series?
Yes - all LTC3410BESC6-x.x variants (e.g., -1.2, -1.5, -1.8, -1.875) share identical SC70-6 pinout, package dimensions, and terminal functions. Only the internal feedback divider differs; therefore, they are mechanically and electrically pin-compatible replacements when output voltage requirements align.
