USRB04 | HIGH PRECISION PRECISION LOW POWER SWITCH USRB04 is a high performance, high precision and low costPWM Power switch for non-isolated buck and buck-boostapplication. It combines a dedicated current mode PWMcontroller with a high voltage power Bipolar in SOP8 package. Itsbuilt-in error amplifier is optimized for good overshoot anddynamic resp including cycle-by-cyclecurrent limiting, output short circuit protection, FB pin open loopprotection, on-chip Over Temperature Protection (OTP), VDDOver Voltage Protection (OVP) and VDD Under Voltage LockoutProtection (UVLO). The tone energy at below 20KHz is minimizedin the design so that audio no; | UTC 友順 | UTC |
