ISL6549
Overview
- Single 12V bias supply (no 5V supply is required)
- Provides two regulated voltages - One synchronous rectified buck PWM controller - One linear controller
- Both controllers drive low cost N-Channel MOSFETs
- Small converter size - Adjustable frequency 150kHz to 1MHz - Small external component count
- Excellent output voltage regulation - Both outputs: ±1% over temperature
- 12V down conversion
- PWM and linear output voltage range: down to 0.8V
- Simple single-loop voltage-mode PWM control design
- Fast PWM converter transient response - High-bandwidth error amplifier
- Undervoltage fault monitoring on both outputs
