MIP2C2 High-Performance IPD for Battery Chargers
I Overview
MIP2C2 is a high-performance IPD designed for 7W battery chargers. It
features built-in protection circuits necessary for compact power source charger
circuitry. This allows a significant reduction in externally connected parts.
MIP2C2 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.
I Features
G Built-in charge protection circuit
Built-in overcurrent, overheating, load shorting and overvoltage protection circuits
G Significantly reduced power consumption with no load*
20mW at 100VAC, 25mW at 240VAC
G High efficiency with rated load*
75% at 100VAC,72% at 240VAC
G Reduced number of parts (12 less than conventional Panasonic models)
* With worldwide input and 5.8V/0.7A output
I Applications
G Chargers (for cellular phones, etc. )
