Product Summary

The M62281P 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. The M62281P IC can operate high speed switching (700kHz max.) with high speed current sense comparator and current limiting circuit.

Parametrics

M62281P absolute maximum ratings: (1)Vcc Supply voltage: 36 V; (2)IOUT Output current Continuous: 150mA; (3)CT terminal Supply voltage: 36V; (4)VEA IN EA IN terminal Supply voltage: 10V; (5)VCLM CLM terminal Supply voltage: -0.3 to +4.0V; (6)VCS CURENT SENSE terminal Supply voltage: -0.3 to +5.8V; (7)Tstg Storage temperature: -20 to +85℃.

Features

M62281P features: (1)CURRENT SENSE terminal separate form CLM terminal makes SMPS strong in noise.; (2)High speed pulse-by-pulse current limiting; (3)Timer type latch protection circuit with OVP(external reset is possible); (4)Soft start operation is possible (with dead time control); (5)Built-in OPAmp for feedback control (photo coupler can be driven); (6)Small start-up current 180μA; (7)Start-up voltage 12.5V, Stop voltage 8.3V.
