DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
M62281P/FP is designed as a high speed current mode
PWM control IC.
This small10 pin package contains many functions and
protection circuits allowing simpler peripheral circuit and
compact set design.
This IC can operate high speed switching (700kHz max.)
with high speed current sense comparator and current
limiting circuit.
