The SC4503 is a 1.3MHz current-mode step-up switching regulator with an integrated 1.4A power transistor. Its high switching frequency allows the use of tiny surface-mount external passive components.
The SC4503 features a combined shutdown and soft-start pin.
The optional soft-start function eliminates high input current and output overshoot during start-up.
The internal compensation network accommodates a wide range of voltage conversion ratios.
The internal switch is rated at 34V making the device suitable for high voltage applications such as Boost and SEPIC.
Features◆ Low Saturation Voltage Switch: 260mV at 1.4A◆ 1.3MHz Constant Switching Frequency◆ Peak Current-mode Control◆ Internal Compensation◆ Programmable Soft-Start◆ Input Voltage Range From 2.5V to 20V◆ Output Voltage up to 27V◆ Uses Small Inductors and Ceramic Capacitors◆ Low Shutdown Current (< 1μA)◆ Low Profile 5-Lead TSOT-23 and 8-Lead 2X2mm MLPD-W packages◆ Fully WEEE and RohS compliant
FeaturesApplications◆ Local DC-DC Converters◆ TFT Bias Supplies◆ XDSL Power Supplies◆ Medical Equipment◆ Digital Cameras◆ Portable Devices◆ White LED Drivers
