Overview
The LM5021 offline PWM controller contains all the features necessary to implement a high-efficiency offline single-ended flyback/forward power converter using current-mode control. The LM5021 features an ultra-low (25μA) startup current to minimize power dissipation in the high-voltage startup network. Skip-cycle mode reduces power consumption under light-load conditions, enabling energy-saving applications (ENERGY STAR, CECP, etc.). Additional features include undervoltage lockout, cycle-by-cycle current limiting, discontinuous mode overload protection, slope compensation, soft-start, and oscillator synchronization. This high-performance 8-pin IC has a total propagation delay of less than 100ns and allows the oscillator to be set to 1MHz with a single resistor.
Applications
- DCM/CCM flyback converters
- Industrial power conversion
- SMPS for smart meters and audio amplifiers
- Building automation and white goods SMPS
- Isolated telecom power supplies
Key features
- Ultra-low startup current (25μA maximum)
- Current mode control
- Cycle-skip mode for reduced standby power
- Single-resistor programmable oscillator

- Direct optocoupler interface
- Maximum duty cycle limiting (80% for LM5021-1, 50% for LM5021-2)
- Slope compensation (LM5021-1 only)
- UVLO protection with hysteresis
- Cycle-by-cycle overcurrent protection
- Hiccup mode for sustained overload protection
- Leading-edge blanking of current sense signal
- Package: VSSOP-8 or PDIP-8
