Description
M62281P/FP is designed as a high speed current mode PWM control IC.
This small 10 pin package contains many functions and protection circuits allowing simpler peripheral circuit and
compact set design.
This IC can operate high speed switching (700 kHz Max.) with high speed current sense comparator and current
limiting circuit.
Features
• 700 kHz applicable to MOS-FET
 Output current Io(peak) = ±1 A
 Totempole output
• CURRENT SENSE terminal separate from 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 OP Amp for feedback control (photo coupler can be driven)
• Small start-up current 180 µA
• Start-up voltage 12.5 V, Stop voltage 8.3 V
Application
Switching Regulator
DC/DC converter
