LTC3410ESC6 Overview
A synchronous buck converter is a DC-DC voltage regulator that reduces a higher input voltage to a lower regulated output using inductive energy storage. The LTC3410 operates as a voltage-mode step-down regulator; its feedback reference supports low-voltage outputs, while its integrated synchronous switch improves conversion efficiency by avoiding the external catch diode used by older non-synchronous buck designs. The switching frequency is 2.25 MHz, which helps keep passive components small.
Key verified features include one adjustable output, a 300 mA output-current rating, a 0.8 V output reference, and operation in the SC70 package identified by distributors as 6-TSSOP, SC-88, or SOT-363. The adjustable topology supports multiple rail requirements when the feedback divider is selected for the target voltage. The internal synchronous switch eliminates an external Schottky diode, reducing board area and assembly complexity.
The datasheet also discusses inductor selection as an application-dependent tradeoff among price, size, and radiated-field or EMI requirements. Surface-mount inductors listed as suitable in the manufacturer documentation should be evaluated together with the switching frequency and output capacitance. Because the component is a switching regulator, layout quality directly affects current-loop behavior, output ripple, stability, and electromagnetic emissions.
Typical uses include compact sensor nodes, portable instruments, communications modules, low-voltage digital rails, and battery-powered equipment. The 300 mA rating is suitable for moderate-load point-of-license or point-of-load conversion, not for high-current processor rails. Confirm the input range, output range, thermal limits, and compensation requirements against the complete manufacturer datasheet before finalizing a design.
For layout, keep the inductor between the switching pins and the output node as recommended in the datasheet, place input decoupling close to the supply pins, and use a compact feedback loop. Verify ripple, startup behavior, load transients, and exposed-pad or ground-return arrangements in the actual board layout. This page combines verified product information, practical application guidance, and substitution constraints without inventing values not present in the supplied sources.

Typical Applications
LTC3410ESC6 is suitable for 6 applications: Portable Sensor Node, Communications Module, Battery-Powered Instrumentation, Embedded Low-Voltage Digital Rail, Low-Voltage Display and Control, Industrial Control Module.
Portable Sensor Node
The LTC3410ESC6 suits compact battery-powered sensor nodes that need a regulated local rail from a higher battery or supply voltage. Its 300 mA current rating is appropriate for sensors, radios, memory, and supervisory circuitry rather than a large processor. The internal synchronous switch removes an external Schottky diode, helping reduce board area. Select the inductor and capacitors using the datasheet guidance, and verify quiescent current and battery-life behavior from the complete electrical specifications.
Recommended
Communications Module
The LTC3410ESC6 can provide a local 300 mA-class rail in compact communications equipment, particularly where a higher supply must be reduced before powering radio, interface, or logic sections. Its 2.25 MHz switching frequency supports small passive components, while the synchronous architecture avoids an external Schottky diode. Designers should inspect switching-node layout and radiated EMI, especially near sensitive RF paths, and confirm the regulator’s output ripple against the receiver or modem requirements.
Recommended
Battery-Powered Instrumentation
The LTC3410ESC6 is appropriate for handheld or portable instrumentation requiring efficient conversion from a battery or higher-voltage source into a compact regulated rail. Its 300 mA rating suits sensors, analog front ends, display logic, and low-power processors when the load is moderate. Efficiency depends on input voltage, output voltage, inductor selection, and load, so calculate the operating profile rather than relying only on the nominal current rating. The SC70 footprint also simplifies dense instrument-board layouts.
Recommended
Embedded Low-Voltage Digital Rail
The LTC3410ESC6 can generate an adjustable low-voltage rail for embedded digital logic when the system operates within the device’s verified current and voltage limits. The 0.8 V feedback reference supports low-output designs, but the complete datasheet must confirm minimum output, startup, and load-transient behavior. Keep feedback routing short and away from the switching node, and verify that the selected inductor and output capacitors meet ripple and stability requirements.
Recommended
Low-Voltage Display and Control
The LTC3410ESC6 is suitable for a compact display, indicator, or control subsystem that requires a regulated rail from a higher supply. The 300 mA capability can cover low-power display drivers, logic, and interface ICs, but not all panel loads without validation. The small SC70 package leaves board area for the display and connectors, while the switching regulator’s ripple and layout must be checked against display-sensitive circuitry. Test startup and load steps on the final PCB.
Recommended
Industrial Control Module
The LTC3410ESC6 can serve as a local point-of-load regulator in industrial control modules where a nominal higher rail must be reduced for sensors, logic, or interface circuits. Its synchronous topology and compact package support dense boards, and the manufacturer documentation discusses inductor selection in relation to size, cost, and EMI. Industrial designs should verify input transients, temperature range, output accuracy, and stability using the complete datasheet rather than relying only on the 300 mA headline rating.

Key Differentiators

- Adjustable low-voltage output support (vs LTC3410)
Design Notes
Use the manufacturer application circuit as the PCB reference. Keep the high-current switching loop compact by placing the inductor, regulator switching pins, input capacitor, and output capacitor in the shortest practical path. Route the feedback divider and feedback trace away from the switching node. At 2.25 MHz, small loop area helps reduce radiated emissions and improve transient behavior.
Select the inductor, input capacitors, and output capacitors for the required 300 mA-class load, output ripple, transient response, and efficiency. The manufacturer states that inductor choice depends on price-versus-size requirements and radiated-field or EMI requirements. Verify inductor saturation current against startup and load-transient peaks rather than using nominal load current alone.
Do not substitute a similarly named LTC3410 orderable code without checking the exact suffix, package marking, and electrical table. Distributor pages use multiple package names for the 6-lead SC70 device, including 6-TSSOP, SC-88, and SOT-363. Confirm that the candidate has the same pin functions, feedback reference, current rating, and compensation requirements before treating it as a drop-in replacement.
Estimate regulator dissipation from the actual input-to-output voltage difference, conversion efficiency, and load current, then verify the result against the package and board thermal limits. The verified data establishes a 300 mA current rating but does not provide the complete thermal-resistance table, so do not use the headline current alone as a guaranteed thermal design point. Measure junction temperature indirectly through board temperature and datasheet limits in the final assembly.
Compliance Information
The supplied verified web data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than assumed.
