The PMP9559 reference design is a compact dual 5.5A POL solution with PMBus in 0.65" by 0.90" size. It showcases CSD87381P power block II with high efficiency and excellent thermal performnce. It has programmable frequency, soft-start, external compensation, adjustable current limit and OCP/OVP/OTP features. It also adds PMBus capability to low current rails. It is suitable for digital high density low-current power rails (<11A).
