GENERAL DESCRIPTION
The BM1430 is a current-mode step-down
DC-DC converter that generates up to 3A output
current at 380kHz switching frequency. The device
utilizes advanced BCD process for operation with
input voltage up to +23V consuming only 55µA in
shutdown mode, the BM1430 is highly efficient
with peak efficiency at 90% when in operation.
Protection features include cycle-by-cycle
current limit, thermal shutdown, and frequency fold
back at short circuit.
The BM1430 is available in SOP-8
package and requires very few external
devices for operation.
APPLICATIONS
TFT LCD Monitors
Portable DVDs
NET CARD
Telecom Power Supplies
DSL and Cable Modems and Routers
LCD TV
It can replace TD1410/MP9141 without
change external components and PCB layout.
If Vin is over 12V, if not use pin7
function , can pull-up a 100K ohm to Vin input
with a pull-up resistor, be better not short to Vin
dirrectly.
