# PCA9450CHNY (Component)
## Description
Power Management IC for iMX8M 5V 6A 6 Buck + 5 LDO
The PCA9450CHNY is a highly integrated Power Management Integrated Circuit (PMIC) from NXP Semiconductors, specifically designed to power the i.MX 8M family of application processors, particularly the i.MX 8M Plus. It integrates multiple high-efficiency DC-DC buck converters, LDO regulators, power sequencing logic, load switching, voltage monitoring, and system control functions into a single device. The PCA9450C variant features a configurable dual-phase 6 A buck regulator for powering high-current processor cores while supporting Dynamic Voltage Scaling (DVS) for optimized power efficiency.
Key Features
Six high-efficiency switching regulators (Buck converters)
PCA9450C variant supports a configurable 6 A dual-phase buck regulator
Three 3 A buck regulators with Dynamic Voltage Scaling (DVS)
Remote-sense capability on major buck outputs for IR-drop compensation
Five integrated LDO regulators
Supports DDR4, LPDDR4, and DDR3L memory configurations
400 mA load switch with active discharge
Dual-channel logic level translator
Integrated 32.768 kHz crystal oscillator driver
Fast-mode Plus (Fm+) 1 MHz I²C interface
Programmable power sequencing and voltage control
Power ON/OFF and Standby/Run mode control inputs
Protection features including UVLO, thermal shutdown, fault monitoring, and soft-start
Operating temperature range: −40°C to +105°C
56-pin HVQFN package (7 mm × 7 mm, 0.4 mm pitch)
Optimized for i.MX 8M Mini, Nano, and Plus processors, especially the i.MX 8M Plus for the PCA9450C variant.
