LCS705LG
Integrated LLC Controller, High-Voltage Power MOSFETs and Drivers
Applications
Product Details
Description
The HiperLCS IC is an integrated LLC power stage incorporating a multi-function controller, high-side and low-side gate drivers, plus two power MOSFETs in a half-bridge configuration. Figure 1 (above) shows a simplified schematic of a HiperLCS based power stage where the LLC resonant inductor is integrated into the transformer.
Product Highlights
Features
- LLC half-bridge power stage incorporating controller, high and low-side gate drives, and high-voltage power MOSFETs
- Eliminates up to 30 external components
- Reduces assembly cost and reduces PCB layout loop areas
- High maximum operating frequency of 1 MHz
- Dramatically reduces magnetics size and allows use of SMD ceramic output capacitors
- Comprehensive fault handling and current limiting
- Programmable brown-in/out thresholds and hysteresis
- Undervoltage (UV) and overvoltage (OV) protection
- Programmable over-current protection (OCP)
- Short-circuit protection (SCP)
- Over-temperature protection (OTP)
- Programmable dead-time for optimized design and improved efficiency
- Programmable burst mode maintains regulation at no-load and improves light load efficiency
- Programmable soft-start time and delay before soft-start
- Single package designed for high-power and high-frequency
- Simple clip attachment to heat sink
- Exposed thermal pad connected to ground potential – no insulators required between package and heat sink
- Staggered pin arrangement for simple PC board routing and high-voltage creepage requirements
