EVQ2026A-R-00A 40V, 300mA, Dual-Channel LDO with Pre-Boost, Digital Interface, and ADC for Digital Diagnosis and Protection Evaluation Board, AEC-Q100
The EVQ2026A-R-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2026A, a dual-channel, low-dropout (LDO) regulator. It contains a boost pre-regulator operating at either 400kHz or 2.2MHz with a digital interface and memory. The device provides phantom power to low-noise amplifiers (LNAs) for active antennas in automotive systems, and can work in 3V cold-crank conditions up to 40V load-dump conditions.
The MPQ2026A delivers up to 300mA per channel with excellent load and line regulation. When the battery is healthy during normal operation, meaning the input voltage (VIN) exceeds the pre-boost turn-on threshold, the pre-boost regulator is completely turned off to reduce the quiescent current (IQ). This makes the MPQ2026A well-suited for power supplies that are always turned on.
The pre-boost regulator provides an integrated MOSFET to further reduce the external component count and EMI. Both the LDO and boost outputs can be configured via the digital interface. The pre-boost regulator’s output voltage (VOUT_BOOST) can be configured between 6.5V and 15.9V. The LDO output voltages (VOUT1 and VOUT2) can be configured between 1V and 13.6V. This protects the LDO output during load dumps.
During bench evaluations, different configurations can be easily obtained via the digital interface, instead of reworking external components. Once the optimal settings have been reached, the multi-page memory can permanently store the settings.
The EVQ2026A-R-00A is a fully assembled and tested evaluation board. The MPQ2026A is available in a QFN-16 (4mmx4mm) package.
