The MPQ7935-AEC1 is a power management IC (PMIC) that integrates four high-efficiency step-down DC/DC converters, a low-dropout (LDO) regulator, and a flexible logic interface.

The DC/DC converters provide constant-on-time (COT) control for fast transient response. The 2.1MHz fixed switching frequency (f_SW) during continuous conduction mode (CCM) greatly reduces external inductance and capacitance. Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.

The I²C interface and one-time programmable (OTP) memory are featured for application flexibility. The output voltage for buck converters 1 and 4 can be adjusted digitally via configurations or in real time. The power-on and power-off sequence are also configurable.

The output voltage for buck converter 2, buck converter 3, and the LDO can be set via external resistors to allow for simplified BOM management. A single orderable part number can be used, even if multiple PMIC configurations are needed.

The MPQ7935-AEC1 is available in a TLGA-29 (4.5mmx4.5mm) package with an exposed pad. It is available in AEC-Q100 Grade 1.

The EVQ7935-LWT-00A evaluation board is designed to demonstrate the capabilities of the MPQ7935-AEC1, a power management IC (PMIC) that integrates four high-efficiency step-down DC/DC converters, a low-dropout (LDO) regulator, and a flexible logic interface.

Constant-on-time (COT) control in the DC/DC converters provides fast transient response. The 2.1MHz fixed switching frequency (f_SW) during continuous conduction mode (CCM) greatly reduces external inductor and capacitor requirements. Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.

The output voltage (V_OUT) is adjustable via the I²C bus or can be preset by the one-time programmable (OTP) memory. The power-on/off sequence is also configurable via the OTP memory and can be controlled via the I²C bus online.

The EVQ7935-LWT-00A is a fully assembled and tested evaluation board. The MPQ7935-AEC1 is available in a TLGA-29 (4.5mmx4.5mm)package with an exposed pad, and is AECQ100 qualified.
