BU90003GWZEVK-101, Evaluation Kit for featuring BU90003GWZEVK, synchronous buck DC/DC converter .While accepting a power supply of 2.3-5.5V, an output of 1.2V can be produced. The IC has internal 250 m-Ohm high-side P-channel MOSFET and 220 m-Ohm low-side N-channel MOSFET and a synchronization frequency range of 3.6MHz to 4.4MHz. A fixed Soft Start circuit prevents in-rush current during startup along with UVLO (low voltage error prevention circuit) and TSD (thermal shut-down detection) protection circuits. An EN pin allows for simple ON/OFF control of the IC to reduce standby current consumption. A MODE pin allows the user to select forced PWM (Pulse Width Modulation) mode or PFM(Pulse Frequency Modulation) and PWM auto change mode utilized power save operation at light load current
