MC34709VK

Power Management - Specialized Overview

The MC34709VK is a power management integrated circuit (PMIC) designed primarily for i.MX 50 and i.MX 53 processors. It features six multi-mode buck regulators, including two single/dual-phase and three single-phase types, supporting up to six independent outputs with PFM/PWM modes and dynamic voltage scaling. The device includes an integrated 5 V boost regulator, eight LDO regulators, and supports USB PHY functions. Auxiliary circuits comprise a 10-bit ADC core with seven general-purpose channels, resistive touchscreen interface, real-time clock, and SPI/I²C serial interfaces.

Power Management - Specialized Procurement Notes

Verify the specific suffix 'V' against official NXP documentation to confirm tape-and-reel packaging specifications and environmental compliance status. Ensure compatibility with the target i.MX processor family and validate board design constraints associated with the 130-pin MAPBGA package before procurement.

Power Management - Specialized Selection Notes

Select this PMIC for designs centered on i.MX 50 or i.MX 53 processors where integrated power management reduces component count. It is suitable for applications not requiring internal battery charging but allowing external charger integration. Consider the 130-pin MAPBGA package for low-cost board routing and verify support for required LDO and buck regulator counts.

Power Management - Specialized Part Context

The MC34709 belongs to NXP's portfolio of power management solutions optimized for complex application processors. It serves as a companion chip that consolidates various voltage regulation, monitoring, and interface functions into a single package, simplifying the power architecture for i.MX-based embedded systems.

Power Management - Specialized Replacement Considerations
