Product details
Overview
LTC3130EMSE#TRPBF from Analog Devices (formerly Linear Technology) is a monolithic 25V, 600mA buck-boost DC/DC converter in a thermally-enhanced 16-lead MSOP package. It operates from 2.4V to 25V input, delivers 1V–25V adjustable output, achieves up to 95% efficiency, and draws only 1.6µA quiescent current in Burst Mode®-enabling ultra-low-power applications such as solar-charged remote sensors and battery-operated instrumentation.
For engineers reviewing the LTC3130EMSE#TRPBF datasheet, LTC3130EMSE#TRPBF pinout, LTC3130EMSE#TRPBF application, or LTC3130EMSE#TRPBF equivalent, key selection criteria include its wide VIN/VOUT range, programmable MPPC for photovoltaic sources, accurate RUN threshold (1.05V), 1.2MHz ultralow-noise PWM operation, and support for EXTVCC input to extend low-VIN capability down to 0.6V.
Technical Context
The LTC3130EMSE#TRPBF employs current-mode control with integrated loop compensation and soft-start, eliminating external compensation components. Its dual-switch buck-boost topology supports seamless transitions between buck, boost, and buck-boost modes-regulating VOUT above, below, or equal to VIN without mode switching artifacts.
It features a dedicated MPPC input that servo-controls inductor current to maintain optimal input voltage from non-ideal sources (e.g., PV panels), and includes an internal 4V LDO for VCC generation powered by VIN or EXTVCC. The RUN comparator enables precise enable/disable sequencing, while PGOOD provides regulated output monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT8330EDD#TRPBF | Higher 40V input rating, 1.5A output, but 25µA IQ (15× higher than LTC3130) | Better suited for industrial 24V rail inputs; less ideal for multi-year battery life | Select when input exceeds 25V or output current >600mA is required; avoid for µA-level energy harvesting |
| TPS63020DSJR | Lower 5.5V max input, 2A output, 30µA IQ, no MPPC, different pinout | Optimized for USB-powered portable devices-not for solar or sub-2.4V start-up | Choose for cost-sensitive consumer applications with stable 3.3V–5.5V inputs; not a functional substitute for LTC3130EMSE#TRPBF's wide-VIN/MPPC capabilities |
Compared with LT8330EDD#TRPBF and TPS63020DSJR, the LTC3130EMSE#TRPBF uniquely combines sub-2.4V start-up, 1.6µA Burst Mode® IQ, hardware MPPC, and 25V operation-making it irreplaceable in solar-charged, long-life, wide-input industrial sensing.

FAQ
What is the minimum input voltage required to start up the LTC3130EMSE#TRPBF?
The LTC3130EMSE#TRPBF achieves start-up from as low as 7.5µW input power-corresponding to ~2.4V at VIN when EXTVCC is unconnected. With EXTVCC ≥3.15V applied, start-up is guaranteed from 0.6V VIN, enabling operation from nearly-dead batteries or low-output energy harvesters.
Does the LTC3130EMSE#TRPBF support fixed output voltages or only adjustable outputs?
The LTC3130EMSE#TRPBF is the standard LTC3130 variant with an FB pin, supporting fully adjustable output from 1.0V to 25V via external resistor divider. It does not include the internal voltage divider of the LTC3130-1; fixed outputs require external feedback network configuration.
How does the MPPC function work on the LTC3130EMSE#TRPBF?
The LTC3130EMSE#TRPBF uses its MPPC pin as a high-impedance input referenced to 1.00V. When connected to a resistor divider from VIN, it dynamically adjusts inductor current to hold VIN at the programmed voltage-maximizing power transfer from PV panels or other impedance-matched sources without software control.
What is the purpose of the ILIM pin on the LTC3130EMSE#TRPBF?
The ILIM pin on the LTC3130EMSE#TRPBF selects the average inductor current limit: grounding it sets 250mA (for low-power, low-heat designs), while tying it to VCC sets 660mA (for full-output capability). This hardware-selectable limit avoids overdesigning magnetics and improves light-load efficiency.
Can the LTC3130EMSE#TRPBF operate without an external inductor?
No-the LTC3130EMSE#TRPBF is a synchronous buck-boost controller requiring an external inductor (typically 6.8µH) connected between SW1 and SW2. It integrates both high-side NMOS switches and drivers but relies on external passive components for energy storage and filtering.
