描述
The ISL6443AEVAL2Z evaluation board highlights the operation of the ISL6443A 300kHz, dual, 180° out-of-phase, step-down pulse width modulating (PWM) and single linear controller in an embedded DC/DC converter application. The ISL6443A is a high performance triple-output controller offering control and protection features for two synchronous buck PWMs and one linear regulator.
特性
- Wide input supply voltage range: Variable 5.6V to 24V, fixed 4.5V to 5.6V
- Three independently programmable output voltages
- Switching frequency 300kHz
- Out-of-phase PWM controller operation reduces required input capacitance and power supply induced loads
- No external current sense resistor - Uses lower MOSFET's rDS(ON)
- Bidirectional frequency synchronization for synchronizing multiple ISL6443A ICs
- Programmable soft-start
- Extensive circuit protection functions
- PGOOD
- UVLO
- Overcurrent
- Over-temperature
- Independent shutdown for both PWMs
- Excellent dynamic response - Voltage feed-forward with current mode control
