LM5033
- Internal High-Voltage (100 V) Start-Up Regulator
- Single Resistor Oscillator Setting
- Synchronizable
- Precision Reference Output
- Adjustable Soft Start
- Overcurrent Protection
- Direct Optocoupler Interface
- 1.5-A Peak Gate Drivers
- Thermal Shutdown
The LM5033 high-voltage PWM controller contains all the features necessary to implement push-pull, half-bridge, and full-bridge topologies. Applications include closed-loop voltage mode converters with a highly regulated output voltage, or open-loop DC transformers such as an Intermediate bus converter (IBC) with an efficiency greater than 95%. Two alternating gate driver outputs with a specified deadtime are provided.
The LM5033 includes a start-up regulator that operates over a wide input range from 15 V to 100 V. Additional features include: precision voltage reference output, current limit detection, remote shutdown, soft start, sync capability, and thermal shutdown. This high-speed IC has total propagation delays less than 100 ns and a 1-MHz capable oscillator.
