BD9302FP
Description
The BD9302FP is a 2-channel step-down switching regulator controller with a 2.5-MHz, 2-A power switch and available for
2.5-MHz high speed switching operation, which facilitates settings of switching frequency with external resistance, supporting
for a wide input voltage range of 6 to 18 V. Furthermore, due to a low reference voltage of 0.6 V, this BD9302FP is an L/C best
suited to high-voltage input/low-voltage output applications, for example, to step down a voltage from 12 V to 1.2 V.
Features
1) A wide input voltage range of 6 V to 18 V
2) Easy switching frequency setting in the range of 200 k to 2.5 MHz.
3) Two built-in power switches of 0.4 Ω, 2 A.
4) 180˚ phase shift
5) Built-in Under Voltage Lock Out circuit
6) Built-in overcurrent protection circuit
7) Built-in Thermal Shutdown circuit
Use
Power supply for DPS requiring two power sources
ADSL modem/plasma display
