ACE716E

ACE716E Max 38V, Variable Frequency Step-up DC/DC Converter 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. Features Up to 90% Efficiency (6 LEDs) Drive up to 10 LEDs with 50mA Drive up to 40 LEDs in total 38V OVP protection True PWM Brightness Control 200mV Feedback Voltage 1A current limit SOT23-6 Package Application Cellphone and Smartp...
