説明
- BU90007GWZ-E2EVK-101, Evaluation Kit for featuring BU90007GWZ, synchronous buck DC/DC converter. While accepting a power supply of 2.3-5.5V, an output of 1.25V can be produced. The IC has internal 250 m-Ohm high-side P-channel MOSFET and 220 m-Ohm low-side N-channel MOSFET (VIN=5V) 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
