diodes advantage www.diodes.com the AP5727 is a high efficiency pwm boost dc/dc converters (integrated switch) designed to generate bias voltages for small oled and tft-lcd display screens. the device can generate up to 30v from a li-ion cell. AP5727 switches at 1.2mhz allowing use of tiny external components. internal compensation, built-in soft-start and integrated switch reduce the component count, pcb area and cost. the AP5727 has a 1.25v feedback voltage and is available in sot23-5, making it compatible with industry standard boost converter used for bias voltage generation. issue number | 001 september 2009 new product announcement boost converter for the bias voltage of small size oled and lcd displays high efficiency: 84% typical longer battery life fast 1.2mhz switching frequency smaller inductor and capacitor size current limit and uvlo protections extra protection for safe operation built-in soft-start function extra protection for safe operation ? reduces inrush current at start up thermal shutdown extra protection for safe operation small size tft-lcd bias power supply oled bias supply for clamshell mobile phone sub- display rf amplifier bias voltage applications AP5727
