High-Performance IPD for Battery ChargersFeaturing built-in frequency jitter necessary for EMI,
while also conserving power during standby!High-Performance IPD for Battery Chargers
MIP2Kx SeriesOverview
MIP2Kx 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.
Features- Built-in jitter function
- Built-in charge protection circuit
Built-in overheating, load shorting and overvoltage protection circuits
ApplicationsChargers (for DSC, etc.), AC adapter
Lineup*1 The electric power mentioned above depends on the transformer specification and ambient conditions. The information should be used only as a guide. When using it within a case, output electric power may be decided by heat of IPD.
*2 All characteristic values are only for reference (still under development).
