説明
- BU90005GWZ-E2EVK-101, Evaluation Kit for featuring BU90005GWZ, synchronous buck DC/DC converter. While accepting a power supply of 2.3-5.5V, an output of 2.5V can be produced. The IC has internal 250 m-Ohm high-side P-channel MOSFET and 220 m-Ohm low-side N-channel MOSFET (at VIN=5V) and a synchronization frequency range of 5.4MHz to 6.6MHz. 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 forced PFM (Pulse Frequency Modulation) mode utilized power save operation at light load current
