Description
OB2235x High Precision Low Cost Power Switch GENERAL .
OB2235x is a high performance, high precision and low cost PWM Power switch for non-isolated buck and buck-boost application.
Features
* including cycle-by-cycle current limiting, output short circuit protection, on-chip Over Temperature Protection (OTP), VDD Over Voltage Protection (OVP), Over Loading Protection(OLP) and VDD Under Voltage Lockout Protection (UVLO). The tone energy at below 20KHz is minimized in the design so that au
