Product details
Overview
LTC3410ESC6-1.65#TRMPBF from Analog Devices (formerly Linear Technology) is a fixed-output, synchronous step-down DC/DC regulator delivering 1.65V at up to 300mA from a 2.5V–5.5V input. It employs constant-frequency current-mode control at 2.25MHz, integrates P- and N-channel MOSFETs, and achieves up to 96% efficiency in portable Li-ion battery-powered systems such as MP3 players and wireless modems.
For engineers reviewing the LTC3410ESC6-1.65#TRMPBF datasheet, LTC3410ESC6-1.65#TRMPBF pinout, LTC3410ESC6-1.65#TRMPBF application, or LTC3410ESC6-1.65#TRMPBF equivalent, key selection criteria include its SC70-6 package footprint, ±2% output voltage accuracy at 100mA load, 26µA quiescent current in Burst Mode, 100% duty-cycle low-dropout capability, and ceramic-capacitor compatibility without external Schottky diode.
Technical Context
The LTC3410ESC6-1.65#TRMPBF implements a constant-frequency (2.25MHz), current-mode synchronous buck architecture with integrated high-side P-channel and low-side N-channel MOSFETs. Its 0.8V internal reference enables precise 1.65V output via internal resistor divider, eliminating external feedback components.
Burst Mode operation reduces quiescent current to 26µA at light loads while maintaining low output ripple (20mVP-P). Overtemperature protection disables both switches above ~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 1.65V ±2% at 100mA load - ensures stable core logic or I/O rail in space-constrained portable devices. |
| Max Output Current | 300mA continuous - supports moderate-power digital subsystems without external boost or parallel regulation. |
| Input Voltage Range | 2.5V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V), USB-powered, and regulated 3.3V/5V supplies. |
| Switching Frequency | 2.25MHz (±0.45MHz) - enables use of sub-5mm inductors (e.g., 4.7µH) and compact 4.7µF ceramic capacitors. |
| Quiescent Current | 26µA in Burst Mode - extends battery runtime in standby or low-activity states (e.g., modem sleep mode). |
| Efficiency Peak | Up to 96% at VIN = 3.6V, VOUT = 1.65V, IOUT = 100mA - minimizes thermal rise and power loss in sealed enclosures. |
| Duty Cycle Limit | 100% - sustains regulated 1.65V output down to VIN ≈ 1.75V, critical for end-of-discharge battery operation. |
Pinout & Package
Package: SC70-6 (6-lead plastic SC70), 2.0mm × 1.25mm × 0.9mm profile, moisture sensitivity level 1, lead-free (Pb-free) termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RUN (Pin 1) | Enable control input | Logic-high (>1.5V) enables regulation; <0.3V forces shutdown (<1µA IQ); must not be left floating. |
| GND (Pins 2, 5) | Power and signal ground | Dual ground pins reduce PCB trace inductance and improve thermal dissipation in high-current paths. |
| SW (Pin 3) | Switch node | Connects to inductor; carries high dv/dt switching waveform - requires tight layout to minimize EMI coupling. |
| VIN (Pin 4) | Main input supply | Accepts 2.5–5.5V; requires local 4.7µF ceramic decoupling placed adjacent to pin for low-impedance AC return. |
| VOUT (Pin 6) | Fixed-output feedback | Internally connected to 1.65V divider - no external resistors needed; used for remote sensing in precision applications. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Eliminates external Schottky diode - reduces BOM count, improves efficiency by 5–10% vs. asynchronous designs. |
| Ceramic capacitor stability | No ESR dependency - enables use of low-ESR, small-footprint X5R/X7R ceramics for <20mVP-P ripple and minimal board area. |
| Burst Mode operation | 26µA IQ with 20mVP-P ripple - maintains regulation during ultra-low-power states without sacrificing transient response. |
| Low dropout (100% duty cycle) | Supports VIN down to ~1.75V while sustaining 1.65V output - extends usable battery capacity by ~15% in Li-ion systems. |
| Overtemperature protection | Thermal shutdown at ~150°C junction - prevents permanent damage during sustained 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 1.65V output, 300mA, 3MHz switching, 17µA IQ - higher frequency but lower max IOUT (300mA vs. 300mA), smaller 1.5mm × 1.5mm DRY package. | Optimized for ultra-small footprint and lowest IQ; less suitable for high-temperature environments due to lower thermal rating (θJA = 290°C/W vs. 250°C/W). | Select when board area is constrained below 2.25mm² and ambient temperature remains <60°C. |
| MAX17222ELT+T | Fixed 1.65V output, 500mA, 2.5MHz, 2.5µA IQ - higher current rating and lower quiescent current, but requires external compensation and lacks 100% duty cycle. | Targeted at energy-harvesting and coin-cell applications; unsuitable for Li-ion dropout extension due to no 100% duty-cycle mode. | Select only if >300mA peak load or sub-10µA IQ is mandatory; avoid where VIN may fall below 1.8V. |
Compared with TPS62231DRYR and MAX17222ELT+T, the LTC3410ESC6-1.65#TRMPBF offers superior thermal performance (250°C/W θJA) and guaranteed 100% duty-cycle operation - critical for maximizing battery utilization in portable industrial instruments and cellular infrastructure edge devices.

FAQ
What is the output voltage tolerance of the LTC3410ESC6-1.65#TRMPBF over temperature and load?
The LTC3410ESC6-1.65#TRMPBF guarantees ±2% output voltage accuracy over the full –40°C to +85°C operating temperature range and at 100mA load. At other loads (50–250mA), line and load regulation contribute ≤0.5% additional error, resulting in typical total variation under ±2.5% across all conditions specified in the datasheet.
Does the LTC3410ESC6-1.65#TRMPBF require external compensation components?
No, the LTC3410ESC6-1.65#TRMPBF uses internal compensation optimized for standard 4.7µF ceramic output capacitors and 4.7µH inductors. Its current-mode architecture and built-in slope compensation ensure stability without external RC networks - simplifying design and reducing bill-of-materials cost.
Can the LTC3410ESC6-1.65#TRMPBF operate with input voltage below 2.5V?
No - the absolute maximum ratings specify minimum input voltage as 2.5V. Operation below this violates the device's UVLO threshold (2.3V rising) and risks improper startup or unregulated output. For sub-2.5V inputs, consider the LTC3642 or alternative ultralow-VIN regulators.
What is the maximum recommended PCB trace length between VIN and CIN for the LTC3410ESC6-1.65#TRMPBF?
For optimal EMI suppression and switching stability, the VIN-to-CIN trace should be ≤2mm in length and ≥0.3mm wide, with CIN placed directly adjacent to Pin 4 (VIN) and Pin 2/5 (GND). Longer traces increase high-frequency ringing and reduce efficiency due to parasitic inductance.
Is the LTC3410ESC6-1.65#TRMPBF RoHS-compliant and halogen-free?
Yes - the LTC3410ESC6-1.65#TRMPBF carries #TRMPBF suffix indicating lead-free (Pb-free), RoHS-compliant, and halogen-free construction per Analog Devices' material declarations. Full compliance documentation is available in the manufacturer's PCN-2019-001 and IPC-1752 reports.
