DP8600C
VOLTAGE MODE PWM CONTROL CIRCUITS
LINEAR INTEGRATED CIRCUIT
DESCRIPTION The DP8600C incorporate on a single monolithic chip all
the functions required in the construction of a pulse-width modulation control circuit.Designed primarily for power supply control, the device offers the systems engineer the flexibility to tailor the power supply control circuitry to its application.
The DP8600C contains an error amplifier,current-limiting amplifier, an on-chip adjustable oscillator, a dead time control comparator,pulse-steering control flip-flop,a 5volt ,1% precision supply regulator,and output control circuits.
The error amplifier exhibits a common-mode Voltage range from -0.3V to VCC-2V.The current-limit amplifier exhibits a common-mode Voltage range from -0.3V to 3V with an offset Voltage of approximately 80 mV in series with the inverting input to ease circuit design requirements. The dead-time control comparator has a fixed offset that provides approximately 5% dead time when .
