NCP1077STGEVB is a fully featured evaluation board developed by On Semi for evaluating NCP1077 - Automotive Isolated 375mA Synchronous Step-Down Controller. It is designed for both Offline and Transition Mode Power Supplies (TMPS). The NCP1077STGEVB belongs to the Evaluation Boards - DC/DC & AC/DC (Offline) SMPS category.

The NCP1077STGEVB is capable of providing a 375mA load current at an output voltage from 1.5V to 24V. The board is designed to be operated using a wide supply voltage range of 5.5V to 36V down to as low as 2V. The reference design also features several protections such as output overvoltage protection (OVP), input undervoltage lockout (UVLO), cycle by cycle current limit (CCL), and overtemperature protection (OTP).

The NCP1077STGEVB utilises the NCP1077 step-down controller which combines the control, drives and provides high-speed and efficient power delivery, as well as superior accuracy. The NCP1077 features On Semi’s proprietary AccuMeter™ Current Mode Control algorithm and provides improved efficiency and good step down performance with low EMI, as well as fast transient response. It also has the capability to protect against output UV detection during the startup condition.

The board also features a simple way to adjust the output current by connecting a resistor. The /SYNC pin allows for the user to synchronise the switching frequency of the NCP1077 with an external clock. To better understand the performance of the NCP1077, a number of pins are made available and can be used to measure the current time, the load current, the output voltage, or the output ripple voltage.

The board also carries a dual layer PCB that is designed to separate control from switching elements, as well as an LCD display which simplifies the evaluation by providing current, temperature, and voltage values. There are also several jumpers, switches and potentiometers which can be used to adjust the operating parameters of the NCP1077.

In conclusion, the NCP1077STGEVB evaluation board is a great way to explore and evaluate the performance of the NCP1077 step-down controller. It provides features such as output OVP, load current limitation, as well as UVLO and overtemperature protection. The board also offers LCD display to assist in evaluation, as well as multiple pins for measuring values. The board is perfect for designing offline and transition mode power supply.
