LTC7103EUHE Integrated Circuit Chip 105V 2.3A Synchronous Step-Down Regulator
Product Overview
The LTC7103EUHE is a high-voltage, low-EMI monolithic synchronous buck DC-DC chip designed for 48V high-voltage bus power distribution in humanoid robots. With an input range of 4.4-105V and continuous output of 2.3A, it can directly step down the robot's high-voltage battery to the 1-15V voltages required by servos, main controllers, and vision sensors.
Key Features
- Wide input range up to 105V, compatible with humanoid robot 36-72V power batteries
- Withstands battery surge impacts, eliminating need for additional surge suppression circuits
- Ultra-short 40 ns on-time maintains constant switching frequency under high-voltage conditions
- Programmable high-frequency range of 200 kHz-2 MHz for compact inductor use
- 5×6 mm heat-dissipation-enhanced QFN package for high power density and thermal management
- Low EMI design compliant with CISPR 25 electromagnetic standard
- Optional burst or jump pulse modes for light loads with 2 μA quiescent current
- Conversion efficiency exceeding 96%
- Comprehensive protection features including input/output overvoltage, current limiting, and over-temperature protection
- Output voltage adjustable from 1V up to input voltage
