DATASHEET EL7516 FN7333 Rev 6.00 600kHz/1.2MHz PWM Step-Up Regulator October 9, 2007 The EL7516 is a high frequency, high efficiency step-up Features voltage regulator operated at constant frequency PWM >90% efficiency mode. With an internal 1.5A, 200m MOSFET, it can deliver up to 600mA output current at over 90% efficiency. The 1.6A, 200m power MOSFET selectable 600kHz and 1.2MHz allows smaller inductors and V > 2.5V IN faster transient response. An external compensation pin 600kHz/1.2MHz switching frequency selection gives the user greater flexibility in setting frequency compensation allowing the use of low ESR Ceramic output Adjustable soft-start capacitors. Internal thermal protection When shut down, it draws <10A of current and can operate 1.1mm max height 8 Ld MSOP package down to 2.5V input supply. These features along with 1.2MHz switching frequency makes it an ideal device for Pb-free plus anneal available (RoHS compliant) portable equipment and TFT-LCD displays. Applications The EL7516 is available in an 8 Ld MSOP package with a TFT-LCD displays maximum height of 1.1mm. The device is specified for operation over the full -40C to +85C temperature range.
