Non-isolated DCDC-CN2203

The CN2203TER is a 3.8V-24V wide input voltage range synchronous buck converter with 30V input over-voltage protection, capable of driving a 0.8A load. The internal integration of two low RDSON power MOS 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 600K, small size inductors and capacitors can be selected, as well as small size SOT23-6L package, which can realize small size power supply solution. With 15uA quiescent operating current and 2uA shutdown current, the CN2203TER is suitable for power supply systems with low power consumption requirements. The CN2203TER features cycle-by-cycle current limit hiccup OCP protection, input OVP, and thermal shutdown.
