LTC3862-2 Overview
Description
The LTC®3862-2 is a two-phase constant frequency, current mode boost and SEPIC controller that drives N-channel power MOSFETs. Two-phase operation reduces system filtering capacitance and inductance requirements.
Key Features
- Fixed Frequency, Peak Current Mode Control
- Internal 10V LDO Regulator
- Lower UVLO Thresholds Allows the Use of MOSFETs Rated at 6V VGS
- Adjustable Slope Compensation Gain
- Adjustable Max Duty Cycle (Up to 96%)
- Adjustable Leading Edge Blanking n ±1% Internal Voltage Reference
- Programmable Operating Frequency with One External Resistor (75kHz to 500kHz)
- Phase-Lockable Fixed Frequency 50kHz to 650kHz
