The MP4247 is a buck-boost converter with two integrated low-side (LS) power switches. The device can deliver up to 100W of peak output power at certain input supplies with excellent efficiency.
The MP4247 is well-suited for USB power delivery (USB PD) applications. The device can work with an external USB PD controller via the I2C interface. The I2C interface and one-time programmable (OTP) memory provide flexible and configurable parameters.
Fault condition protections include constant current (CC) current limiting, output over-voltage protection (OVP), and thermal shutdown (TSD).
The MP4247 requires a minimal number of readily available, standard external components, and is available in a QFN-20 (3mmx5mm) package.
