DESCRIPTION
The UC184xA family of control ICs provides all the necessary features to implement off-line fixed-frequency, current-mode switching power supplies with a minimum of external components. The current mode architecture demonstrates improved load regulation, pulse-by-pulse current limiting and inherent protection of the power supply output switch. The IC includes: A bandgap reference trimmed to ±1 accuracy, an error amplifier, a current sense comparator with internal clamp to 1V, a high current totem pole output stage for fast switching of power MOSFETs, and an externally programmable oscillator to set frequency and maximum duty cycle. The undervoltage lock-out is designed to operate with 250μA typ. start-up current, allowing an efficient bootstrap supply voltage design.
KEY FEATURES
■ LOW START-UP CURRENT. (0.5mA max.)
■ TRIMMED OSCILLATOR DISCHARGE CURRENT. (See Product Highlight)
■ OPTIMIZED FOR OFF-LINE AND DC-TO-DC CONVERTERS.
■ AUTOMATIC FEED FORWARD COMPENSATION.
■ PULSE-BY-PULSE CURRENT LIMITING.
■ ENHANCED LOAD RESPONSE CHARACTERISTICS.
■ UNDER-VOLTAGE LOCKOUT WITH HYSTERESIS.
■ DOUBLE PULSE SUPPRESSION.
■ HIGH-CURRENT TOTEM POLE OUTPUT.
■ INTERNALLY TRIMMED BANDGAP REFERENCE.
■ 500KHz OPERATION.
■ LOW RO ERROR AMPLIFIER.
APPLICATIONS
■ ECONOMICAL OFF-LINE FLYBACK OR FORWARD CONVERTERS.
■ DC-DC BUCK OR BOOST CONVERTERS.
■ LOW COST DC MOTOR CONTROL.
