Product details
Overview
LTC3130EMSE#PBF from Analog Devices (formerly Linear Technology) is a monolithic, current-mode buck-boost DC/DC converter optimized for ultra-low-power applications. It delivers up to 600mA output current, supports input voltages from 2.4V to 25V (or down to 0.6V with EXTVCC), provides adjustable 1V–25V output, operates at 1.2MHz PWM frequency, and achieves just 1.6µA quiescent current in Burst Mode - enabling long-life battery operation in remote sensors and portable military radios.
For engineers reviewing the LTC3130EMSE#PBF datasheet, LTC3130EMSE#PBF pinout, LTC3130EMSE#PBF application, or LTC3130EMSE#PBF equivalent, key selection criteria include its pin-selectable 850mA/450mA inductor current limit, accurate RUN comparator threshold (1.05V typ), programmable MPPC for solar energy harvesting, power-good indicator, and thermally enhanced 16-lead MSOP package with exposed pad.
Technical Context
The LTC3130EMSE#PBF employs a current-mode control architecture with integrated 1.2MHz oscillator, soft-start, and built-in loop compensation - eliminating external compensation components. Its dual NMOS switch topology enables true buck-boost operation, regulating VOUT above, below, or equal to VIN without polarity reversal.
It features an ultralow-noise PWM architecture, MPPC circuitry that servo-inputs to maximize power extraction from photovoltaic panels or other high-impedance sources, and independent VCC regulation powered by either VIN or EXTVCC - allowing operation down to 1V input when EXTVCC is used.
Key Specifications

FAQ
What is the minimum input voltage required to start up the LTC3130EMSE#PBF?
The LTC3130EMSE#PBF achieves start-up from as low as 7.5µW - corresponding to ~2.4V at VIN when EXTVCC is unconnected. With EXTVCC ≥ 3.15V applied, start-up is guaranteed down to 0.6V at VIN. This enables operation directly from partially discharged batteries or low-output energy harvesters. The RUN pin threshold (1.05V) and internal UVLO ensure predictable turn-on behavior across temperature.
How does the MPPC function work on the LTC3130EMSE#PBF?
The MPPC pin on the LTC3130EMSE#PBF accepts a resistor divider from VIN to set a target input voltage (e.g., 5V for a solar panel's max power point). When the divider voltage drops below 1.00V (typ), the controller reduces inductor current to servo VIN to that programmed value. With <20nA input bias and 1.00V ±50mV reference accuracy, it enables precise, self-contained MPPT without external op-amps or microcontrollers - a core differentiator of the LTC3130EMSE#PBF.
Can the LTC3130EMSE#PBF operate in both buck and boost modes simultaneously?
Yes - the LTC3130EMSE#PBF is a true buck-boost converter with a 4-switch topology that seamlessly transitions between buck, boost, and buck-boost regions based on input/output relationship. When VIN ≈ VOUT, it operates in buck-boost mode with both switches active; when VIN > VOUT, it favors buck operation; when VIN < VOUT, it favors boost. No mode selection or external control is needed - the IC automatically manages duty cycle and phase timing to maintain regulation across all three regions.
What is the purpose of the EXTVCC pin on the LTC3130EMSE#PBF?
The EXTVCC pin on the LTC3130EMSE#PBF provides a secondary input to the internal 4V VCC regulator. When driven with 3.15V–25V (e.g., from VOUT or a dedicated auxiliary rail), it powers the IC's internal circuitry - reducing VIN quiescent current to 600nA and enabling operation down to 1V VIN. This is essential for maximizing efficiency in buck-dominant applications and extending usable battery voltage range beyond standard UVLO limits.
Does the LTC3130EMSE#PBF require external compensation components?
No - the LTC3130EMSE#PBF integrates full loop compensation, eliminating the need for external Type-II or Type-III compensation networks. Combined with built-in soft-start and current-mode control, this simplifies design, reduces BOM count, and improves stability across load and input variations. Layout best practices (short, low-inductance SW and PGND traces; proper ceramic input/output capacitance) remain critical for optimal transient response and EMI performance.
