1 General description
The PCA9460 is a single chip Power Management IC (PMIC) designed to support ultra-low-power applications
where standby power and overall power consumption of power management IC is critical. The PCA9460 is
designed to be paired with i.MX 8ULP processor which enables such key applications. It provides power supply
solutions for low power wearable application where size and efficiency are critical.
The PCA9460 comes equipped with four buck regulators, five LDOs and additional load switches. This design
offers the most flexible configuration for i.MX 8ULP or other processors to enable the ultra-low-power system
design. Each buck regulator has been designed with ultra-low Iq current to reduce standby current. Two
buck regulators support smart Dynamic Voltage Scaling (DVS), which allows the system designed to set the
right voltage on the processors the PCA9460 is powering. This process minimize power consumption that
is controlled through the PMIC_STBY_REQ pin or MODE[2:0] pins. Five LDOs have 300 nA low quiescent
current. One LDO is available for SNVS core power supply, one 250 mA LDO is to regulate to low output
voltage from buck regulator output. Three 250 mA LDOs supply power to the processor and peripheral devices.
Four 150 mΩ load switches switch power for peripheral devices. These switches can be configured as an LED
driver with two different blink modes.
The PCA9460 is offered in a 42-bump wafer-level CSP package, 2.86 mm x 2.46 mm, 0.4 mm pitch.
