Product details
Overview
LTC3130EMSE-1#TRPBF 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 at 2.4V) with EXTVCC, making it ideal for long-life battery-powered sensors and portable military radios.
For engineers reviewing the LTC3130EMSE-1#TRPBF datasheet, LTC3130EMSE-1#TRPBF pinout, LTC3130EMSE-1#TRPBF application, or LTC3130EMSE-1#TRPBF 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 energy-constrained systems.
Technical Context
The LTC3130EMSE-1#TRPBF employs a current-mode, monolithic buck-boost architecture with dual NMOS switches (SW1/SW2), bootstrapped gate drives (BST1/BST2), and integrated 4V LDO for internal circuitry (VCC). Its MPPC loop compares a resistor-divider voltage on the MPPC pin to a 1.00V reference to dynamically adjust inductor current and maintain optimal source voltage - critical for photovoltaic panel interfaces.
It features pin-selectable operating modes: MODE = GND enables Burst Mode® (1.6µA IQ) for ultra-low-load efficiency; MODE = VCC forces fixed-frequency 1.2MHz PWM. Output voltage is set via VS1/VS2 logic inputs (0/0 → 1.8V, 0/VCC → 3.3V, VCC/0 → 5.0V, VCC/VCC → 12V), eliminating external feedback resistors while maintaining ±2% output accuracy over temperature.

FAQ
What output voltages does the LTC3130EMSE-1#TRPBF support without external resistors?
The LTC3130EMSE-1#TRPBF supports four factory-programmed fixed outputs: 1.8V (VS1=0V, VS2=0V), 3.3V (VS1=VCC, VS2=0V), 5.0V (VS1=0V, VS2=VCC), and 12V (VS1=VCC, VS2=VCC). These selections are implemented via internal resistor dividers - no external feedback components are required, reducing BOM count and layout sensitivity.
How does the MPPC function work on the LTC3130EMSE-1#TRPBF?
The LTC3130EMSE-1#TRPBF's MPPC pin compares an external resistor-divider voltage from VIN to a precise 1.00V internal reference. When the divider voltage falls below this threshold, the controller reduces inductor current to raise VIN toward the programmed maximum power point - enabling autonomous optimization of power extraction from photovoltaic panels or other variable-output sources without MCU involvement.
Can the LTC3130EMSE-1#TRPBF operate from input voltages below 2.4V?
Yes - the LTC3130EMSE-1#TRPBF supports operation down to 0.6V when powered via the EXTVCC pin (enabled at ≥3.15V). This allows regulation from deeply discharged batteries or low-voltage energy harvesters. Startup still requires ≥2.4V on PVIN or VIN, but once running, EXTVCC sustains operation even if PVIN drops below 1V.
What is the thermal requirement for the LTC3130EMSE-1#TRPBF in MSOP package?
The LTC3130EMSE-1#TRPBF in the 16-lead MSOP package has θJA = 40°C/W, contingent on soldering the exposed pad (Pin 17) directly to the PCB ground plane. Failure to do so increases thermal resistance significantly, risking thermal shutdown under 600mA load at elevated ambient temperatures. A minimum 4cm² copper pour under the pad is recommended for full-rated performance.
Does the LTC3130EMSE-1#TRPBF require external compensation components?
No - the LTC3130EMSE-1#TRPBF 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/VS1/VS2 resistors - accelerating design cycle and improving reliability.
