EV1529DR-00A 2.7-4.2V Fixed Frequency Step-Up Converter LCD Backlight Plus Flash Evaluation Evaluation Board QFN16
The MPS EV1529DR-00A is an evaluation board built around the MP1529 for bench characterisation of the device in its intended topology. It operates from a 2.7 V to 4.2 V input and switches at 1.2 MHz. The board carries the device in its QFN16 package.
The EV1529DR-00A evaluation board is designed to drive 2 strings of up to 4 backlight LEDs to 30mA and a 4-LED flash string to 150mA from a single Lithium-Ion battery.

Design Notes
- The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
- Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
- Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
- Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
