The device is a high-voltage converter that smartly integrates an 800 V avalanche rugged power MOSFET with PWM current-mode control. The power MOSFET with 800 V breakdown voltage allows extended input voltage range to be applied, as well as to reduce the size of the DRAIN snubber circuit. This IC is capable of meeting the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation under light load. The Zero-Power mode (ZPM) feature enables the IC to work in an idle state, where the system is totally shutdown. An MCU can be easily connected to the IC for smart ZPM management and it can be supplied by the IC itself during the idle state. The design of flyback, buck and buck boost converters is supported. The integrated HV startup, sense FET, error amplifier and oscillator with jitter allow a complete application to be designed with a minimum component count. In flyback non isolated topology, a negative output voltage is easily set thanks to the integrated error amplifier with separate ground.
主要特性
- Smart stand-by architecture using the Zero Power Mode (ZPM)
- ZPM management by MCU easily realizable
- 800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to be covered
- Embedded HV startup and sense-FET
- Current mode PWM controller
- Drain current limit protection (OCP)
- Wide supply voltage range: 4.5 V to 30 V
- Self-supply option allows to remove the auxiliary winding or bias components
- Minimized system input power consumption:
- Less than 4 mW @ 230 VAC in ZPM
- Less than 10 mW @ 230 VAC in no-load condition
- Less than 400 mW @ 230 VAC with 250 mW load
- Jittered switching frequency reduces the EMI filter cost
- 60 kHz ±7% (type L)
- 120 kHz ±7% (type H)
- Embedded E/A with 1.2 V reference and separate ground for easy negative voltage setting
- Protections with automatic restart: overload/short circuit (OLP), max. duty cycle counter, VCC clamp
- Pulse-skip protection to prevent flux-runaway
- Embedded thermal shutdown
- Built in soft start for improved system reliability
