Detalhes do produto
Single inductor 4-switch buck-boost controller
On-the-fly bidirectional operation with independent control of voltage and current on both ends
Proprietary algorithm for smoothest mode transition
MOSFET drivers with adaptive shoot-through protection
Wide input voltage range: 4.5V to 40V
Wide output voltage range: 0.8V to 40V
Supports pre-biased output with SR soft-start
Programmable frequency: 100kHz to 600kHz
Supports parallel operation current sharing with cascade phase interleaving
External sync with clock out or frequency dithering
External bias for higher efficiency supports 5V - 36V input
Output and input current monitor
Selectable PWM mode operation between PWM/DE/Burst modes
Low shutdown current: 2.7μA
Complete protection: OCP, SCP, OVP, OTP, and UVP
- Dual-level OCP protection with average current and pulse-by-pulse peak current limit
- Selectable OCP response with either hiccup or constant current mode
- Negative pulse-by-pulse peak current limit
