ACE716E

Max 38V, Variable Frequency Step-up DC/DC Converter

VER 1.2

Description

The ACE716E is a high efficiency step-up converter with an internally integrated 40V power MOSEFT.

It runs with an optimal 0.8MHz frequency that enables use of small external components while still

providing best efficiencies. It has an internal current limit as high as 1A, and it can drive up to 10 LEDs at

50mA output current. The incorporated 25-100KHz true PWM-Dimming feature by EN pin can be used to

digitally program the LED current. For maximum protection, the ACE716E has an internal OVP protection

at 38V to prevent the chip from damages when the LED string is not connected to the output.

ACE716E is available in a space-saving SOT23-6 package.
