Product details
Overview
LTC3130EMSE-1#PBF from Analog Devices (formerly Linear Technology) is a 25V, 600mA monolithic 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 VOUT from 1V to 25V - above, below, or equal to VIN - and supports input as low as 0.6V (startup from 2.4V), making it ideal for long-life battery-powered instrumentation and solar-charged IoT sensors.
For engineers reviewing the LTC3130EMSE-1#PBF datasheet, LTC3130EMSE-1#PBF pinout, LTC3130EMSE-1#PBF application, or LTC3130EMSE-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 low-quiescent-power buck-boost regulation in space-constrained industrial and portable designs.
Technical Context
The LTC3130EMSE-1#PBF employs a current-mode, synchronous buck-boost topology with dual NMOS switches (SW1/SW2), integrated 4V LDO for internal VCC generation, and programmable MPPC that servo-controls input voltage via a resistor divider on the MPPC pin. Its 1.2MHz fixed-frequency PWM or selectable Burst Mode® operation enables ultra-low-noise performance with tiny 22nF bootstrap capacitors and low-profile inductors.
Unlike the adjustable LTC3130, the -1 variant replaces the FB pin with VS1/VS2 pins to select one of four factory-trimmed output voltages (1.8V, 3.3V, 5.0V, or 12V) using logic-level inputs - eliminating external feedback resistors while maintaining ±2% output accuracy over temperature. RUN threshold hysteresis (100mV) and accurate UVLO enable robust start-up control from weak or variable sources like photovoltaic panels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 0.6V to 25V (start-up from 2.4V); enables operation from single-cell LiFePO₄ or multi-cell PV arrays without pre-regulation. |
| VOUT Options | Four fixed outputs: 1.8V/3.3V/5.0V/12V (±2% accuracy); eliminates feedback resistor network and reduces BOM count. |
| IQ (Burst Mode) | 1.6µA typical at 12VIN/5VOUT; extends battery life in always-on sensor nodes beyond 10 years on a single CR2032. |
| Switching Frequency | 1.2MHz (±20%); allows use of ≤10µH inductors and ceramic output caps <22µF, minimizing solution footprint. |
| Current Limit | 660mA average inductor current limit (typical); supports 600mA continuous load with thermal derating in MSOP package. |
| MPPC Reference | 1.00V ±50mV; enables precise maximum power extraction from solar cells by regulating input voltage to VMPP. |
| Shutdown IQ | 500nA; ensures negligible drain during deep sleep, critical for energy-harvesting systems with intermittent sources. |
Pinout & Package
Package: 16-lead plastic MSOP (3mm × 4.9mm), exposed pad (Pin 17) soldered to PCB ground for thermal and electrical integrity (θJA = 40°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power Ground | Common return for PGND and analog ground; must be connected directly to exposed pad and system ground plane. |
| 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-boost cycle. |
| SW1 (Pin 3) | Primary Switch Node | Connects to one end of power inductor; requires short, wide PCB trace to minimize switching losses and EMI. |
| PVIN (Pin 4) | Main Power Input | Accepts up to 25V; bypassed with ≥4.7µF ceramic cap close to pin; supports high-impedance sources like solar cells. |
| VIN (Pin 5) | VCC Regulator Input | Supplies internal 4V LDO; minimum 1µF ceramic decoupling required; enables EXTVCC-assisted operation down to 1VIN. |
| RUN (Pin 6) | Enable/UVLO Comparator Input | Turns on converter when >1.05V (hysteresis 100mV); tied to VIN for always-on, or resistor divider for programmable start threshold. |
| VCC (Pin 7) | Internal 4V Regulator Output | Bypass with ≥4.7µF ceramic cap; powers internal circuitry and may supply ≤2mA external loads (e.g., ADC reference). |
| MPPC (Pin 8) | Maximum Power Point Control Input | Resistor divider from PVIN sets target input voltage; noise-sensitive - keep trace short and shielded from SW nodes. |
| SW2 (Pin 16) | Secondary Switch Node | Connects to other end of power inductor; symmetric layout with SW1 essential for balanced conduction and low EMI. |
| BST2 (Pin 15) | Bootstrap Supply for SW2 High-Side Driver | Connects via 22nF capacitor to SW2; identical function to BST1 but for second switch leg. |
| VOUT (Pin 14) | Regulated Output | Delivers selected fixed voltage (1.8V/3.3V/5.0V/12V); requires ≥4.7µF ceramic output capacitor for stability. |
| PGOOD (Pin 13) | Open-Drain Power-Good Indicator | Pulls low when VOUT drops >7.5% below regulation; requires external pull-up for system monitoring or sequencing. |
| EXTVCC (Pin 12) | Alternate VCC Input | Accepts 3.15V–25V; reduces VIN quiescent draw and enables sub-1V VIN operation when tied to VOUT or auxiliary rail. |
| MODE (Pin 11) | Operation Mode Select | Ground = Burst Mode® (ultra-low IQ); VCC = fixed-frequency PWM (low-noise, predictable ripple). |
| VS1 / VS2 (Pins 10 / 9) | Output Voltage Selection Inputs | Logic-level inputs (0/VCC) set VOUT per Table 1: 1.8V (0,0), 3.3V (VCC,0), 5.0V (0,VCC), 12V (VCC,VCC). |
Key Features

FAQ
What output voltages does the LTC3130EMSE-1#PBF support?
The LTC3130EMSE-1#PBF provides four factory-trimmed, pin-selectable output voltages: 1.8V, 3.3V, 5.0V, and 12V. These are configured using logic-level inputs on VS1 (Pin 10) and VS2 (Pin 9), with combinations defined in Table 1 of the datasheet. Unlike the adjustable LTC3130, the LTC3130EMSE-1#PBF does not use an FB pin - eliminating external resistors and improving accuracy and reliability in production.
How does the MPPC function work on the LTC3130EMSE-1#PBF?
The MPPC (Maximum Power Point Control) function on the LTC3130EMSE-1#PBF uses an internal 1.00V reference to servo the input voltage (PVIN) to a user-defined level set by a resistor divider from PVIN to GND on the MPPC pin. When the divider voltage falls below ~1.0V, the controller reduces inductor current to raise PVIN - enabling optimal power extraction from non-ideal sources like solar panels. The LTC3130EMSE-1#PBF implements this entirely in analog hardware, requiring no firmware or external components.
Can the LTC3130EMSE-1#PBF operate from a single-cell Li-ion battery?
Yes - the LTC3130EMSE-1#PBF supports input voltages as low as 0.6V (with startup from 2.4V) and can regulate outputs up to 25V. When powered from a discharged single-cell Li-ion (as low as 2.7V), it delivers full 600mA output. With EXTVCC tied to VOUT, it can even start from inputs below 1V - making it compatible with deeply discharged or hybrid energy storage systems where the LTC3130EMSE-1#PBF serves as the primary system regulator.
What is the purpose of the MODE pin on the LTC3130EMSE-1#PBF?
The MODE pin (Pin 11) selects between two operating modes: grounding the pin enables Burst Mode® operation (1.6µA IQ, ideal for light-load efficiency), while tying it to VCC forces fixed-frequency 1.2MHz PWM operation (lower output ripple, deterministic EMI profile). An internal 3MΩ pull-down ensures default Burst Mode® if left unconnected after startup - simplifying designs where lowest quiescent current is mandatory.
Does the LTC3130EMSE-1#PBF require external compensation components?
No - the LTC3130EMSE-1#PBF integrates full loop compensation, soft-start circuitry, and gate drivers, eliminating the need for external compensation networks or timing capacitors. This reduces bill-of-materials count, PCB area, and design validation effort. All stability and transient response characteristics are guaranteed across the full input/output range and temperature (-40°C to 125°C), as verified in the datasheet's Typical Performance Characteristics section.
