Monolithic Power Systems (MPS) EV3314A-C-00A Converter Evaluation Board
Monolithic Power Systems (MPS) EV3314A-C-00A Converter Evaluation Board is designed to demonstrate the capabilities of the MP3314A. The MP3314A is a boost converter with six-channel current sources that drives WLED arrays for LCD panels in virtual reality (VR) backlighting applications. The MPS MP3314A supports a 3V to 30V input voltage (VIN) range, and an output voltage (VOUT) up to 43V. The device uses peak current mode control and pulse-width modulation (PWM) control to maintain boost converter regulation.
Features
- Six channels with a maximum of 80mA/channel
- Integrated 50V, 130mΩ on resistance [RDS(ON)] low-side MOSFET (LS-FET)
- 3V to 30V VIN range
- Up to 43V VOUT
- 187.5mV LED regulation voltage at 20mA
- 2% LED current (ILED) accuracy, <3% ILED matching at 20mA
- 312kHz, 625kHz, or 1250kHz selectable switching frequencies (fSW)
- I2C brightness control
- Manual mode and direct PWM dimming
- PWM1 and PWM2 input signals to control channels 1 to 3 and channels 4 to 6, respectively
- Configurable switching slope and Frequency Spread Spectrum (FSS) function to improve EMI
- One-Time Programmable (OTP) memory for customizable default register values
- LED open/short protection
- Over-temperature protection
- Over-Current Protection (OCP), inductor, or diode short protection
Applications
- Virtual Reality (VR) displays
- LCD panel backlighting
