This is High-Performance IPD with Frequency Jitter for Small Charger / Adapter.
High-Performance IPD (Integrated Passive Device) refers to a class of miniaturized passive electronic components that are integrated into a single chip or substrate alongside active components, such as integrated circuits (ICs) or microelectromechanical systems (MEMS). IPDs are used in various applications to provide essential passive functions like filtering, matching, decoupling, and impedance transformation.
The MIP2K2 series is a high-performance IPD designed for 15W battery chargers and featuring built-in frequency jitter function at PWM control. It features built-in protection circuits necessary for compact
power source charger circuitry. This allows a significant reduction in externally connected parts. It provides PWM control when a normal load is applied and intermittent control with low load. This results in greater efficiency for very low to maximum loads, while also conserving power during standby.
