Non-isolated DCDC-CN2213

The CN2213TER is a 5.5V-24V wide input voltage range synchronous buck converter with a fixed output voltage of 5V, 30V input overvoltage protection, and is capable of driving a 0.8A load. The internal integration of two low RDSON power tubes reduces conduction loss and improves efficiency. The chip adopts peak current mode control, which can achieve excellent dynamic performance and also makes the peripheral compensation circuit simple. Since the switching frequency is fixed at 600kHz, small-size inductors and capacitors can be selected, as well as small-size SOT23-6L packages, which can realize small-size power solutions. Feedback resistors are integrated inside the chip, reducing the number of peripheral devices. With a closed-loop no-load 7uA operating current and 2uA shutdown current, the CN2213TER is suitable for power supply systems with low power consumption requirements. The CN2213TER features cycle-by-cycle current limit hiccup OCP protection, short circuit protection, input OVP, and thermal shutdown.
