LTC3410ESC6-1.875#TRPBF - 1.875V 300mA Buck Regulator
MPN: LTC3410ESC6-1.875#TRPBF ✓ AktifLTC3410ESC6-1.875#TRPBF Ringkasan
A synchronous buck converter is a switching voltage regulator that reduces an input voltage to a lower regulated output using controlled high-frequency switching. It belongs to the DC-DC converter category, which is part of power management integrated circuits. Synchronous operation is especially useful in portable and space-constrained equipment because it can provide high conversion efficiency with fewer external components.
The LTC3410ESC6-1.875#TRPBF provides a fixed 1.875V output, supports up to 300mA, and operates at approximately 2.25MHz. Verified distributor information also identifies low-ripple Burst Mode operation, a 26µA quiescent current specification, efficiency up to 96%, and output ripple around 20mV peak-to-peak under specified conditions. These characteristics suit battery-powered, sensor, portable-instrument, and embedded low-voltage rail applications.
The fixed 1.875V version is appropriate when the downstream circuit requires a stable low-voltage rail without external feedback adjustment. The 6-pin SC-70 package minimizes board area, while the high switching frequency helps keep passive components compact. Designers should verify inductor selection, capacitor ripple current, thermal conditions, and startup behavior against the manufacturer datasheet for the intended VIN, VOUT, and load conditions.
This page summarizes verified manufacturer and distributor information, practical application guidance, comparison criteria, and drop-in alternatives that may help engineers evaluate the LTC3410ESC6-1.875#TRPBF for compact low-power power designs.

Aplikasi Umum
LTC3410ESC6-1.875#TRPBF cocok untuk 6 aplikasis: Low-Voltage Sensor Rail, Battery-Powered Embedded Device, Portable Measurement Instrument, Compact Industrial Control Module, Audio or Low-Noise Analog Rail, Battery Charging and Power Management.
Low-Voltage Sensor Rail
The LTC3410ESC6-1.875#TRPBF is suitable for powering compatible low-voltage sensor front ends from a 2.5V to 5.5V source. Its fixed 1.875V output and up-to-300mA capability provide a compact regulated rail without an external feedback adjustment. The internal synchronous switch removes the Schottky diode, reducing external parts. Designers should account for startup behavior, load transients, and the approximately 20mVp-p ripple specification in precision sensor circuits.

Battery-Powered Embedded Device
The converter suits compact battery-powered equipment where a regulated low-voltage rail is required and board area is limited. Its 26µA Burst Mode quiescent-current specification helps reduce standby consumption, while the synchronous topology supports conversion efficiency up to 96% under suitable operating conditions. The 1.875V rail should be checked against the battery range, load startup demand, regulator dropout behavior, and the system’s allowable ripple.
Direkomendasikan
Portable Measurement Instrument
The LTC3410ESC6-1.875#TRPBF can provide a compact 1.875V rail for portable measurement or instrumentation circuits. Its 2.25MHz switching frequency helps keep passive components small, while the fixed output reduces the need for external adjustment. For measurement accuracy, evaluate the measured ripple under the intended VIN and load, verify the output capacitor ESR requirement, and separate sensitive analog paths from switching-current paths where possible.
Direkomendasikan
Compact Industrial Control Module
The regulator is appropriate for small control modules that accept a 2.5V to 5.5V source and require a local 1.875V rail. The synchronous buck architecture reduces the external diode count and can improve efficiency compared with a basic asynchronous implementation. Industrial temperature, transient response, and EMC requirements should be checked independently because the supplied data does not establish a full industrial temperature range or EMC qualification.
Direkomendasikan
Audio or Low-Noise Analog Rail
The LTC3410ESC6-1.875#TRPBF may be considered for compatible low-voltage analog or audio circuitry when its measured ripple is acceptable. The verified output ripple is approximately 20mVp-p under stated conditions, and the device operates at 2.25MHz. It is not an ultra-low-noise linear regulator, so analog designs should compare the measured switching spectrum and output impedance with the noise requirements of the audio or measurement front end.
Direkomendasikan
Battery Charging and Power Management
The LTC3410ESC6-1.875#TRPBF can provide a regulated auxiliary rail in a battery-powered system, but it is not a battery charger by itself. Its 2.5V to 5.5V input and fixed 1.875V output make it suitable for a post-input regulation stage when the source is already within that range. Confirm charger architecture, reverse-current behavior, startup sequencing, and load sharing before using it in a power-path design.

Diferensiator Kunci
- Fixed 1.875V output (vsLTC3410ESC6-1.8#TRPBF)
- Compact synchronous architecture (vsLTC3410B)
- Low-power operating feature (vsLP5900TLX-1.8)
Catatan Desain
Use the verified 300mA rating as the nominal design target, but check the datasheet limits for minimum on-time, current limit, dropout, and inductor ripple at the selected VIN. The reported 380mA capability at VIN 3V comes from a distributor snippet and should not replace the manufacturer’s application limits. Confirm that the downstream load can tolerate the approximately 20mVp-p output ripple during startup and load transients.
Keep the high-current switching loop compact by placing the input capacitor, switching node, inductor, output capacitor, and power-ground return according to the manufacturer layout guidance. The 2.25MHz switching frequency can create fast-edge current loops and EMI. Avoid routing sensitive analog signals beneath the switch node and use adequate ground-plane continuity around the SC-70 device.
Do not substitute LTC3410ESC6-1.8#TRPBF for the 1.875V version without checking rail-margin requirements, since the nominal outputs differ by 75mV. Also verify the active polarity and sequencing requirements of EN, the output-capacitor ESR requirements, and the startup behavior. The package marking TRPBF identifies the lead-free ordering suffix but does not by itself establish RoHS or full regulatory compliance.
Informasi Konformitas
The orderable suffix TRPBF and distributor description identify the part as lead-free, but the supplied data does not explicitly confirm RoHS, REACH, halogen-free, or conflict-minerals status. Verify current declarations with Analog Devices or the selected distributor.
