ML4818CP - Brand New ML IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
GENERAL DESCRIPTION
The ML4818 is a complete phase modulation control IC suitable for full bridge
soft switching converters. Unlike conventional PWM circuits, the phase
modulation technique allows for zero-voltage switching transitions and square
wave drive across the transformer. The IC modulates the phases of the two
sides of the bridge to control output power.
The ML4818 can be operated in current mode. The delay times for the outputs
are externally programmable to allow the zero-voltage switching transitions to
take place.
Pulse-by-pulse current limit, integrating fault detection, and soft start
reset are provided. The under-voltage lockout circuit features a 6V hysteresis
with a low starting current to allow off-line start up with a low power bleed
resistor. A shutdown function powers down the IC, putting it into a low
quiescent state.
FEATURES
■ Full bridge phase modulation zero voltage switching circuit with
programmable ZV transition times
■ Constant frequency operation to 500kHz
■ Current mode operation
■ Cycle-by-cycle current limiting with integrating fault detection and restart
delay
■ Precision buffered 5V reference (+1%)
■ Four 1.5A peak current totem-pole output drivers
■ Under-voltage lockout circuit with 6V hysteresis
■ Power DIP package allows higher dissipation
