The MPQ70240FS is a complete power management solution that integrates three high-efficiency step-down DC/DC converters and a low-noise low-dropout (LDO) regulator and flexible logic interface. Unique architecture with two first-stage buck converters redefines the size, efficiency, and EMI of high-resolution camera modules.
Constant-on-time control (COT) with phase-locked loop (PLL) provides fast transient response and a stable frequency. A 2.2MHz fixed switching frequency (fSW) during continuous conduction mode (CCM) greatly reduces the required external inductance and capacitance. Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.
