3 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.
