EVQ1531-M-00A Evaluation Kit Low Power, Triple Output Step-Up Plus Charge Pump for TFT Bias
The EVQ1531-M-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP1531 triple output step-up converter with charge-pumps.
The MP1531 includes a 250KHz fixed-frequency step-up converter and a positive and negative linear regulator. The linear regulators are powered via charge-pumps driven by the step-up converter switch node.
A single on/off control enablesall3 outputs. The outputs are internally sequenced at power-on for ease of use. An internal soft-start prevents overloading the input source at startup. Cycle-by-cycle current limit reduces component stress.
