DESCRIPTION

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.

FEATURES

● 700kHz applicable to MOS-FET

• Output current Io(peak) = ±1A

• Totem pole output

● CURRENT SENSE terminal separate form CLM terminal makes SMPS strong in noise.

● High speed pulse-by-pulse current limiting

● Timer type latch protection circuit with OVP(external reset is possible)

● Soft start operation is possible (with dead time control)

● Built-in OPAmp for feedback control (photo coupler can be driven)

● Small start-up current 180µA

● Start-up voltage 12.5V, Stop voltage 8.3V

APPLICATION

• Switching Regulator

• DC-DC converter
