The LBK0504 is a miniaturized step-down converter featuring small size and high efficiency. The power module integrates the power management integrated circuit (PMIC) and the inductor in a compact 2.0 mm x 2.5 mm x 1.1 mm package. The package is optimized for automated assembly by standard surface-mount pick-and-place equipment.
The LBK0504 also features an I2C interface which can be used to configure the protection circuits, soft-start circuit, I2C address, and timeout. The protection circuits include input under-voltage lockout (UVLO), over-temperature protection (OTP), output over-voltage and under-voltage protection (OVP and UVP), and cycle-by-cycle current limit.
The device can be used in parallel to multiply the output current (up to 4 phases in parallel). The LBK0504 features ultra low-noise performance, making it a primary candidate for low-noise applications.

Description
The LBK0504 is a miniaturized step-down converter featuring small size and high efficiency.
TheLBK0504 is a miniaturized, high-efficiency 4A step-down DC-DCconverter from 2.3 V to 5.5 V input range. The LBK0504 integrates both a power management integrated circuit (PMIC) and an inductor in to a 2.0mm×2.5mm×1.1mm package compatible with standard automated pick-and place equipment.
The LBK0504 combines a PWM peak-current control synchronous buck architecture with a flexible digital interface. Through I2C, users can program the soft-start, address, and timeout, and monitor protection parameters. These protections include in put under-voltage lockout (UVLO), over-temperature protection (OTP), output over-voltage protection(OVP), output under-voltage protection (UVP), and cycle-by-cycle current limit.
The LBK0504 supports multi-phase parallel operation. Up to four phases can be combined to extend the total output current capability to 16A forscalable power architectures. Delivering ultra-low output ripple and noise performance, the LBK0504 excels in noise-sensitive applications including optical transceivers, point-of load converters in computing, 5G small cells, and medical devices.
