Monolithic Power Systems MP4059 | Demoboard EV4059-S-00A
90VAC~265VAC, 21V/350mA Single-Stage Deep PWM Dimming Solution
Overview
| Topology | Flyback Converter |
| Input voltage | 90-265 V |
| Switching frequency | 0.2-60 kHz |
| Output 1 | 21 V / 0.35 A |
| IC revision | 1.0 |
Description
The EV4059-S-00A Evaluation Board is designed to demonstrate the capabilities of MP4059. The MP4059 is a single power stage and PFC controller targeting at LED deep dimming applications. It can regulate a constant current to an LED load over a 1% to 100% dimming range without flicker or shimmer. It is a primary side controller without any secondary side feedback components and the opto-coupler to significantly simplify LED driver design. The MP4059 integrates power factor correction and works in valley switching mode to achieve high efficiency
Features
- 1% to 100% dimming range
- Ultra low standby loss, typically less than 50mW at 230Vac.
- Universal input
- Fast start up
- No flicker
- Low audible noise
- Valley switching mode for good efficiency
- Good PF(typically >0.9)
- Primary-side Over-Current protection
- Output OVP/SCP
- Under-voltage lockout(UVLO)
- Thermal Shutdown (160oC/100oC)
- SOIC-8 Package
Typical applications
- LED PWM dimming
