OB2235NASP - High Precision Low Cost Power Switch

Download the OB2235NASP datasheet PDF. This datasheet also covers the OB2235NAP-On variant, as both devices belong to the same high precision low cost power switch family and are provided as variant models within a single manufacturer datasheet.

Description

OB2235x 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 Mosfet in DIP7,DIP8&SOP8 package.

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 audio noise is eliminated during operation. OB2235x is offered in DIP7,DIP8&SOP8 package.

OB2235x High Precision Low Cost Power Switch GENERAL DESCRIPTION OB2235x 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 Mosfet in DIP7,DIP8&SOP8 package. Its built-in error amplifier is optimized for good overshoot and dynamic response for low cost and component count. With precise inner resistor divider, precise reference of EA, constant voltage regulation of 12V at universal AC input can be guaranteed. Frequency reduction and burst mode control is implemented for high efficiency at light load. Good EMI performance is achieved with On-Bright proprietary frequency shuffling technique and soft gate driver design.
