USRB04 Datasheet (UTC) - HIGH PRECISION PRECISION LOW POWER SWITCH

USRB04, HIGH PRECISION PRECISION LOW POWER SWITCH

USRB04 is a high performance, high precision and low cost PWM Power switch for non-isolated buck and buck-boost application.

It combines a dedicated current mode PWM controller with a high voltage power Bipolar in SOP8 package.

Its built-in error amplifier is optimized for good overshoot and dynamic

USRB04 Features

* including cycle-by-cycle current limiting, output short circuit protection, FB pin open loop protection, on-chip Over Temperature Protection (OTP), VDD Over Voltage Protection (OVP) and VDD Under Voltage Lockout Protection (UVLO). The tone energy at below 20KHz is minimized in the design so that aud
