28-V Output Voltage Boost Converter with Power Diode and Isolation Switch

28-V Output Voltage Boost Converter with Power Diode and Isolation Switch - TLV61046A
 

Description

The TLV61046A is a highly integrated boost converter designed for applications such as PMOLED panel, LCD bias supply and sensor module. The TLV61046A integrates a 30-V power switch, an input to output isolation switch, and a rectifier diode. It can output up to 28 V from input of a Li+ battery or two alkaline batteries in series.

The TLV61046A operates with a switching frequency at 1.0 MHz. This allows the use of small external components. The TLV61046A has an internal default 12-V output voltage setting by connecting the FB pin to the VIN pin. Thus it only needs three external components to get 12-V output voltage. The TLV61046A has typical 980-mA switch current limit. It has 7-ms built-in soft start time to reduce the inrush current. When the TLV61046A is in shutdown mode, the isolation switch disconnects the output from input to minimize the leakage current. The TLV61046A also implements output short circuit protection, output over-voltage protection and thermal shutdown.

The TLV61046A is available in a 6-pin 3-mm x 3-mm SOT23-6 package.
