Product details
Overview
LTC3130IMSE#TRPBF from Analog Devices (formerly Linear Technology) is a monolithic, current-mode buck-boost DC/DC converter optimized for ultra-low-power, wide-input applications. It delivers up to 600mA output current with 1.6µA quiescent current in Burst Mode®, supports input voltages from 2.4V to 25V (or down to 0.6V with EXTVCC), regulates output from 1V to 25V, and integrates programmable maximum power point control (MPPC) for solar energy harvesting. It is widely used in battery-powered instrumentation and low-power sensor nodes.
For engineers reviewing the LTC3130IMSE#TRPBF datasheet, LTC3130IMSE#TRPBF pinout, LTC3130IMSE#TRPBF application, or LTC3130IMSE#TRPBF equivalent, key selection criteria include its 1.2MHz ultralow-noise PWM operation, pin-selectable 850mA/450mA average inductor current limit, accurate RUN comparator threshold (1.05V typ), integrated soft-start, and thermally enhanced 16-lead MSOP package with exposed pad.
Technical Context
The LTC3130IMSE#TRPBF employs a synchronous four-switch buck-boost topology with internal NMOS power switches (RDS(ON) = 0.35Ω typ at VCC = 4V), enabling regulation where VOUT can be above, below, or equal to VIN. Its current-mode control loop includes built-in compensation and supports both fixed-frequency PWM (1.2MHz typ) and ultralow-IQ Burst Mode® operation.
It features dual bootstrap supplies (BST1/BST2), an external VCC input (EXTVCC) for sub-1V start-up, MPPC feedback referenced to 1.00V ±5%, and a precision RUN comparator with 100mV hysteresis. The device implements thermal shutdown, soft-start (12ms typ), and power-good indication with –5% VOUT threshold accuracy.

Pinout & Package
Package: 16-lead plastic MSOP with exposed thermal pad (Pin 17 = GND). Requires soldering of exposed pad to PCB ground plane for thermal performance (θJA = 40°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1, Exposed Pad) | Power and signal ground reference | Must be soldered to large PCB ground plane; serves as primary thermal path and PGND return. |
| BST1 (Pin 2) | Bootstrap supply for SW1 high-side gate drive | Connects via 22nF capacitor to SW1; enables full enhancement of internal high-side NMOS switch. |
| SW1 (Pin 3) | High-side switch node (buck path) | Connects to one end of power inductor; requires short, low-inductance PCB trace to minimize EMI and switching loss. |
| PVIN (Pin 4) | Main power input for converter power stage | Accepts 2.4–25V input; requires ≥4.7µF local ceramic bypass; bulk capacitance needed for high-ESR sources. |
| VIN (Pin 5) | Input to internal VCC LDO regulator | Supplies internal circuitry; minimum 1µF ceramic decoupling required; enables VCC regulation when EXTVCC is unused. |
| RUN (Pin 6) | Enable comparator input | Turns on converter when >1.05V (rising); 0.2–0.85V logic thresholds enable precise VIN UVLO programming. |
| VCC (Pin 7) | Internal 4V regulated supply output | Bypass with ≥4.7µF ceramic; powers internal logic; can source ≤2mA for external biasing (raises min VIN by ~60mV). |
| MPPC (Pin 8) | Maximum Power Point Control input | Reference voltage = 1.00V ±5%; connects to resistor divider from VIN to set optimal input voltage for PV panels or fuel cells. |
| VS2/FB (Pin 9) | Feedback input (LTC3130) or VOUT select (LTC3130-1) | This part is LTC3130 (not -1), so FB pin sets VOUT via resistor divider; input bias current <10nA enables high-R dividers. |
| VS1/ILIM (Pin 10) | Current limit select (LTC3130) or VOUT select (LTC3130-1) | For LTC3130: ILIM = GND → 450mA avg limit; ILIM = VCC → 850mA avg limit; logic thresholds: 0.35V/1.1V. |
| MODE (Pin 11) | Operation mode control | MODE = GND → Burst Mode® (ultra-low IQ); MODE = VCC → fixed 1.2MHz PWM; internal 3MΩ pull-down prevents floating. |
| EXTVCC (Pin 12) | Secondary VCC input | Accepts 3.15–25V; reduces VIN quiescent draw and enables start-up from <1V sources; bypass with 4.7µF if not tied to VOUT. |
| PGOOD (Pin 13) | Open-drain power-good indicator | Pulls low when VOUT drops >5% below regulation; requires external pull-up; active during UVLO/shutdown if VIN/EXTVCC present. |
| VOUT (Pin 14) | Regulated output voltage | Delivers up to 600mA; requires ≥4.7µF ceramic output capacitor; low-ESR ceramics recommended for ripple suppression. |
| BST2 (Pin 15) | Bootstrap supply for SW2 high-side gate drive | Connects via 22nF capacitor to SW2; enables full gate drive for second high-side NMOS in boost path. |
| SW2 (Pin 16) | High-side switch node (boost path) | Connects to other end of power inductor; symmetric layout with SW1 critical for balanced conduction and EMI control. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63020DSJR | Lower max IOUT (3A vs 0.6A), higher IQ (30µA vs 1.6µA), no MPPC, 3.5mm × 3.5mm QFN | Targets higher-current portable devices (e.g., tablets); unsuitable for >5-year battery life or solar MPPT. | Select TPS63020DSJR only when >1A output or smaller footprint is mandatory and ultra-low IQ is not required. |
| MAX20406AATG+ | Higher IQ (2.5µA), integrated FETs rated for 2.5A, no MPPC, 2.5mm × 2.5mm WLP | Optimized for space-constrained consumer wearables; lacks precision RUN threshold and MPPC for energy harvesting. | Choose MAX20406AATG+ for compact, cost-sensitive designs where 2.5µA IQ suffices and solar integration is unnecessary. |
Compared with TPS63020DSJR and MAX20406AATG+, the LTC3130IMSE#TRPBF uniquely combines sub-2µA quiescent current, programmable MPPC, and accurate RUN threshold-making it the only option capable of >10-year battery life with solar assist in remote sensing applications.

FAQ
What is the minimum input voltage required to start up the LTC3130IMSE#TRPBF?
The LTC3130IMSE#TRPBF achieves start-up from as low as 2.4V when powered solely from VIN. With EXTVCC enabled (≥3.15V), start-up is possible from VIN as low as 0.6V. This capability is essential for deep-discharge battery operation and solar panel cold-start conditions. The RUN pin must exceed 1.05V for full enablement.
How does the MPPC function work in the LTC3130IMSE#TRPBF?
The LTC3130IMSE#TRPBF's MPPC pin compares a resistor-divider voltage from VIN against an internal 1.00V reference. When the divider voltage falls below ~0.95V, the controller reduces inductor current to servo VIN toward the programmed MPP voltage. Input bias is <20nA, enabling high-impedance dividers with minimal power loss-critical for low-light solar harvesting.
Can the LTC3130IMSE#TRPBF regulate output voltages below its input voltage?
Yes. The LTC3130IMSE#TRPBF is a true buck-boost converter with synchronous four-switch architecture, enabling seamless regulation where VOUT is less than, greater than, or equal to VIN. For example, it can generate 3.3V from a 5V input (buck), 12V from a 3.6V input (boost), or 5V from a 4.2V input (buck-boost transition region) without mode switching artifacts.
What is the purpose of the EXTVCC pin on the LTC3130IMSE#TRPBF?
The EXTVCC pin on the LTC3130IMSE#TRPBF provides a secondary input to the internal VCC regulator. When driven with 3.15–25V (e.g., from VOUT or a separate rail), it powers the IC's internal circuitry, reducing VIN quiescent current and enabling start-up from VIN as low as 0.6V. This is vital for applications like solar chargers where the input source cannot directly supply the IC's bias current.
Is the LTC3130IMSE#TRPBF pin-compatible with the LTC3130-1 variant?
No. While both share the same 16-lead MSOP package and most pin functions, the LTC3130IMSE#TRPBF (standard LTC3130) uses Pin 9 as FB and Pin 10 as ILIM, whereas the LTC3130-1 uses those pins as VS2 and VS1 for fixed-output selection. Interchanging them will result in incorrect feedback or current limiting behavior and potential regulation failure.
