DESCRIPTION
converters. This IC has 2 outputs employing a totem-pole circuit with peak output current 1.2 A, and is capable of
directly driving a power MOS FET. As a result, it has been possible to realize primary side control of an active-clamp
type converter on a single chip.
Note It is necessary to obtain license from Vicor Corporation before using the PC1909 in an active-clamp type circuit.
FEATURES
• 2 on-chip outputs; for Q and Q
• Capable of directly driving a power MOS FET
• Drive supply voltage range: 7 to 24 V
• On-chip remote control circuit
• On-chip pulse-by-pulse overcurrent protection circuit
• On-chip overvoltage latch circuit
