Product Introduction

The PFC/PWM controller combined with UCC28521 and UCC28528 provides any off-line power required with IEC1000-3-2 harmonics to reduce the full control function of the system. By combining into a single device, significant performance and cost advantages of the PFC and PWM stages of control and drive signals are benefits.

On the basis of UCC28511, the average current mode control architecture of the new device is used to feed forward the input voltage. The main difference of the UCC28521/28 is the trailing edge/trailing edge (transmission electron microscopy/transmission electron microscopy) as the stage modulation scheme of the circuit/PWM. Different UCC28528 PWM segments as UCC28521 for their non-rotating bulk voltage drop. The UCC28528 is an ancillary for low-power design of PWM.

characteristic

PFC and PWM power stages are provided in one device
PFC at trailing edge, trailing edge PWM modulation
Built-in PFC and PWM sequencing steering up
2, source and 3 sinks are suitable for PFC and PWM gate drives in both stages
A typical rise time of 16-ns and a fall time of 7 ns is a load of 1-NF
Features of PFC:
- Continuous on-mode operation controlled by average current mode
- High linear multiplier power factor of nearly 1
- Input voltage feedforward implementation
- Improved load transient response
- Precise power limits
- Zero power detection
Features of PWM:
- Peak current mode controls operation
- 1:1 PFC: Pulse width modulation frequency option
- Programmable maximum duty cycle limit up to 90%
- Programmable soft start
apply
- Efficient server and desktop supplies
- AC to DC converter for efficient telecommunications
