AP5502 60V DC/DC Buck-Boost Configuration Converter
Description
The AP5502 is a current mode DC/DC converter with an internal 2.5A, 60V
switch specifically designed to drive LEDs. The AP5502 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 200KHz (SOP-8 (FD))
/500KHz (TDFN3X3-10) operating frequency, the external inductor and in-
put/output capacitors can all be small. Dimming can be either analog,
PWM, or PWM converting to analog with an external capacitor.
The AP5502 is available in SOP-8 (FD), TSSOP-14 (FD) & TDFN3X3-10
package.
