水下机器人3D打印机专用DCDC恒流IC
LED升降压恒流驱动IC大功率可外挂MOS
Description
The AP5503 is a current mode DC/DC converter with
outside power NMOS designed to drive LEDs. The
AP5503 operates as a LED driver in buck, boost and
buck-boost mode. The LED current is externally programmable with a 120mV sense resistor. With a
500KHz operating frequency, the external inductor and
input/output capacitors can all be small. Dimming can
be either analog, PWM, or PWM converting to analog
with an external capacitor.
The AP5503 is available in MSOP-10 (FD) package.
