Product details
Overview
LTC7880EUKG#TRPBF from Analog Devices is a dual-output, 60V synchronous step-up DC/DC controller with PMBus/I²C digital power system management, constant-frequency current-mode control, and independent power-good/FAULT signaling per channel. It supports up to 6-phase PolyPhase® operation, programmable gate drive (6.3V–9V), and operates from 5V–40V input while sustaining regulation down to 2.5V after startup - used in high-reliability industrial power supplies and automotive start-stop systems.
For engineers reviewing the LTC7880EUKG#TRPBF datasheet, LTC7880EUKG#TRPBF pinout, LTC7880EUKG#TRPBF application, or LTC7880EUKG#TRPBF equivalent, key selection considerations include its dual 60V output capability, ±0.5% output voltage accuracy over temperature, integrated 16-bit ADC/12-bit DAC, internal EEPROM with ECC and fault logging, and 52-lead QFN package with exposed thermal pad.
Technical Context
The LTC7880EUKG#TRPBF implements analog current-mode control with digitally configurable loop compensation, enabling stable regulation across wide VIN (5V–40V) and VOUT (up to 60V) ranges. Its two independent boost channels support discontinuous (pulse-skipping) or continuous conduction mode, with programmable switching frequency (50kHz–500kHz) and phase alignment via SYNC input.
Digital management is implemented through a PMBus-compliant I²C interface, supporting telemetry read-back of input/output voltage/current, temperature, and faults; programmable soft-start/stop, sequencing, margining, OV/UV/OC thresholds; and nonvolatile storage of configuration parameters in on-chip EEPROM with CRC protection and fault logging.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC7804IUH#TRPBF | Single-output, 60V, no PMBus interface; analog-only configuration with fewer protection features. | Lacks digital telemetry, EEPROM, and dual-channel independence - suitable only for cost-sensitive, non-managed boost applications. | Select when digital management, fault logging, or dual-rail control are unnecessary and BOM cost is critical. |
| MP2918GL-Z | Single-output, 40V max, PMBus v1.3 compliant; lower integration (no internal EEPROM, no 16-bit ADC). | Supports basic telemetry but lacks PolyPhase® sharing, digital servo, and ±0.5% accuracy over temperature. | Choose for simpler 12V→24V/36V conversion where advanced power management is not required. |

FAQ
What is the maximum input voltage the LTC7880EUKG#TRPBF can withstand during transients?
The LTC7880EUKG#TRPBF supports transient input voltages up to 65V on VIN0 and VIN1 pins, and up to 74.8V on TG0/TG1 pins per Absolute Maximum Ratings. This robustness enables reliable operation in automotive and industrial environments with load-dump or inductive kickback events. The device's internal charge pump and gate driver architecture maintain regulation even during sustained 40V input conditions.
Does the LTC7880EUKG#TRPBF support pre-biased output startup?
Yes, the LTC7880EUKG#TRPBF supports controlled startup into pre-biased outputs via its digital soft-start algorithm and current-mode control architecture. The device monitors output voltage during ramp-up and adjusts duty cycle to avoid reverse current flow, as confirmed in the Typical Application section and Startup Waveforms (Figure 7880 TA01b). This feature is essential for hot-swap and redundant power systems.
How is fault logging implemented in the LTC7880EUKG#TRPBF?
Fault logging in the LTC7880EUKG#TRPBF uses on-chip EEPROM with ECC to store timestamps, fault type (OV/UV/OC/OT), channel ID, and associated telemetry (VOUT, IOUT, temperature) at time of event. Each log entry is CRC-protected, and up to 32 fault records can be retained. Logging is enabled automatically on FAULT assertion and accessible via PMBus READ_EEPROM command - no host intervention required.
Can the LTC7880EUKG#TRPBF operate with only one output enabled?
Yes, the LTC7880EUKG#TRPBF allows independent enable/disable of each channel via RUN0 and RUN1 pins or PMBus ON_OFF_CONFIG command. When one channel is disabled, the other continues full operation with unchanged loop compensation, telemetry, and protection - verified in the Operation section under "Power-Up and Initialization" and "Shutdown" subsections.
What is the purpose of the SHARE_CLK pin on the LTC7880EUKG#TRPBF?
The SHARE_CLK pin on the LTC7880EUKG#TRPBF distributes a synchronized clock signal to coordinate switching across multiple LTC7880 devices or phases in PolyPhase® configurations. It ensures deterministic phase offset (e.g., 0°, 60°, 120°) between channels, enabling precise current sharing and reduced input/output ripple - a requirement validated in the "PolyPhase Load Sharing" and "Phase-Locked Loop" sections of the datasheet.
