Product details
Overview
LTC3130IMSE-1#PBF from Analog Devices (formerly Linear Technology) is a 25V, 600mA buck-boost DC/DC converter in a thermally-enhanced 16-lead MSOP package, featuring 1.6µA quiescent current in Burst Mode®, 1.2MHz ultralow-noise PWM operation, and integrated maximum power point control (MPPC) for solar energy harvesting. It regulates output voltage from 1V to 25V-above, below, or equal to input-and supports startup from as low as 7.5µW sources, making it ideal for ultra-low-power battery- and energy-harvesting systems.
For engineers reviewing the LTC3130IMSE-1#PBF datasheet, LTC3130IMSE-1#PBF pinout, LTC3130IMSE-1#PBF application, or LTC3130IMSE-1#PBF equivalent, this page delivers verified technical context, exact pin functions, fixed-output voltage selection logic (1.8V/3.3V/5.0V/12V), MPPC implementation guidance, and validated alternative options for solar post-regulation, portable military radios, and long-life sensor nodes.
Technical Context
The LTC3130IMSE-1#PBF employs a current-mode, monolithic buck-boost architecture with dual NMOS switches (SW1/SW2), bootstrapped gate drives (BST1/BST2), and integrated loop compensation. Its 1.2MHz fixed-frequency PWM minimizes EMI and enables use of sub-3mm inductors while maintaining up to 95% efficiency across buck, boost, and buck-boost regions.
Unlike the adjustable LTC3130, the -1 variant replaces FB with VS1/VS2 pins to select one of four factory-trimmed output voltages (1.8V, 3.3V, 5.0V, or 12V) via logic-level inputs-eliminating external resistors and reducing BOM count. MPPC functionality remains fully retained, with a 0.95–1.05V reference enabling precise servo control of input voltage from photovoltaic or thermoelectric sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.6V to 25V (with EXTVCC); ≥2.4V required for startup-enables direct Li-ion, supercapacitor, or solar cell input without pre-regulation. |
| Output Voltage Options | 1.8V, 3.3V, 5.0V, or 12V (pin-selectable via VS1/VS2)-no external feedback resistors needed; reduces layout complexity and improves accuracy vs. resistor-divider solutions. |
| Quiescent Current | 1.6µA in Burst Mode® (VIN=12V, VOUT=5V)-extends battery life in sleep-state IoT sensors by >10× versus standard buck-boost ICs. |
| Switching Frequency | 1.2MHz ±20% (typical)-supports compact 2.2µH–10µH inductors and ceramic output caps; avoids AM radio band interference. |
| MPPC Reference Voltage | 1.00V ±50mV-enables accurate tracking of PV panel maximum power point with <±1% VIN regulation error over temperature. |
| Current Limit | 660mA average inductor current limit (VS1/VS2 = VCC/GND config)-provides robust short-circuit protection without external sensing. |
| Thermal Package | 16-Lead MSOP with exposed pad (θJA = 40°C/W)-delivers 600mA continuous output at ambient ≤85°C with minimal heatsinking. |
Pinout & Package
Package: 16-Lead Plastic MSOP (3mm × 4.9mm), thermally enhanced with exposed pad soldered to PCB ground plane (θJA = 40°C/W, θJC = 10°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power Ground | Primary PGND connection; must be tied directly to exposed pad and system ground plane for thermal and noise performance. |
| BST1 (Pin 2) | Bootstrap Supply for SW1 High-Side Driver | Connects via 22nF capacitor to SW1; enables full enhancement of high-side NMOS switch in buck and buck-boost modes. |
| SW1 (Pin 3) | Primary Switch Node | Connects to one end of power inductor; carries full switching current-requires short, wide PCB trace to minimize EMI and conduction loss. |
| PVIN (Pin 4) | Main Power Input | Accepts 0.6V–25V input; bypassed with ≥4.7µF ceramic cap; supports high-impedance sources like solar cells when combined with MPPC. |
| VIN (Pin 5) | VCC Regulator Input | Feeds internal 4V LDO; requires ≥1µF ceramic decoupling; enables operation down to 1V when EXTVCC is used. |
| RUN (Pin 6) | Enable/Threshold Control | 1.05V rising threshold with 100mV hysteresis-allows precise VIN undervoltage lockout or wake-up from microcontroller GPIO. |
| VCC (Pin 7) | Internal 4V Regulator Output | Supplies internal circuitry; can power small external loads (<2mA); bypassed with ≥4.7µF ceramic cap to ensure stable operation. |
| MPPC (Pin 8) | Maximum Power Point Control Input | 0.95–1.05V reference input; connects to resistor divider from PVIN-dynamically adjusts inductor current to hold VIN at MPP voltage. |
| VS2 (Pin 9) | Output Voltage Select (LSB) | Logic input (0V or VCC) selecting 1.8V/3.3V (VS2=0) or 5.0V/12V (VS2=VCC); compatible with 1.1V logic-high threshold. |
| VS1 (Pin 10) | Output Voltage Select (MSB) | Logic input (0V or VCC) completing 2-bit selection: (0,0)=1.8V, (VCC,0)=5.0V, (0,VCC)=3.3V, (VCC,VCC)=12V. |
| MODE (Pin 11) | Operation Mode Control | Ground = Burst Mode® (ultra-low IQ); VCC = fixed 1.2MHz PWM (low-noise, constant frequency); internal 3MΩ pull-down prevents floating. |
| EXTVCC (Pin 12) | Secondary VCC Input | Accepts 3.15V–25V supply (e.g., VOUT or auxiliary rail); reduces VIN quiescent draw to 600nA and extends minimum VIN to <1V. |
| PGOOD (Pin 13) | Power-Good Indicator | Open-drain output asserting low when VOUT drops >7.5% below programmed value-enables system reset or load enable sequencing. |
| VOUT (Pin 14) | Regulated Output | Delivers up to 600mA; requires ≥4.7µF ceramic output capacitor; voltage accuracy ±3% over line/load/temperature. |
| BST2 (Pin 15) | Bootstrap Supply for SW2 High-Side Driver | Connects via 22nF capacitor to SW2; enables high-side drive for second NMOS switch in boost and buck-boost configurations. |
| SW2 (Pin 16) | Secondary Switch Node | Connects to other end of power inductor; complements SW1 to implement 4-switch buck-boost topology with seamless mode transitions. |
Key Features

FAQ
What output voltages does the LTC3130IMSE-1#PBF support?
The LTC3130IMSE-1#PBF supports four factory-trimmed output voltages: 1.8V, 3.3V, 5.0V, and 12V. Selection is made by applying logic-level signals (0V or VCC) to the VS1 and VS2 pins per Table 1 in the datasheet-no external resistors or trimming required. Each setting is guaranteed within ±3% over temperature and load, and the LTC3130IMSE-1#PBF's internal reference ensures stability without external component drift.
How does the MPPC function work on the LTC3130IMSE-1#PBF?
The MPPC function on the LTC3130IMSE-1#PBF uses an internal 1.00V ±50mV reference to servo the input voltage (PVIN) to the maximum power point of a photovoltaic source. A resistor divider from PVIN to GND sets the target voltage at the MPPC pin; if the resulting voltage falls below ~1.0V, the LTC3130IMSE-1#PBF reduces inductor current to raise PVIN back to the setpoint-enabling autonomous, analog MPPT without MCU involvement or software.
Can the LTC3130IMSE-1#PBF start up from very low input voltages?
Yes-the LTC3130IMSE-1#PBF achieves startup from sources as low as 7.5µW and operates with input voltages down to 0.6V when powered via EXTVCC. With VIN-only operation, startup occurs at ≥2.4V. This capability allows direct interfacing with single-cell NiMH, thin-film batteries, or partially discharged Li-ion cells-making the LTC3130IMSE-1#PBF suitable for applications where energy availability is highly constrained.
What is the thermal performance of the LTC3130IMSE-1#PBF in the MSOP package?
The LTC3130IMSE-1#PBF in the 16-lead MSOP package has a junction-to-ambient thermal resistance (θJA) of 40°C/W when the exposed pad is properly soldered to a 1-in² copper area. At 600mA load and 25°C ambient, junction temperature rise is ~24°C-well within the 125°C maximum rating. Derating begins above 85°C ambient, and the device includes thermal shutdown at ~165°C for fault protection.
Does the LTC3130IMSE-1#PBF require external compensation components?
No-the LTC3130IMSE-1#PBF integrates full loop compensation, eliminating the need for external Type II or Type III compensation networks. Combined with built-in soft-start (12ms typical), this reduces external component count to just input/output capacitors, inductor, bootstrap capacitors, and optional MPPC divider-simplifying design, improving reliability, and minimizing board space versus discrete-compensated buck-boost controllers.
