Product Details
| DESCRIPTION The LT®3473/LT3473A are micropower step-up DC/DC converters with integrated Schottky diode and output disconnect circuitry in low profile DFN packages. The small package size, high level of integration and the use of tiny SMT components yield a solution size of less than 50mm2. The internal 1A switch allows the device to deliver 25V at up to 80mA from a Li-Ion cell, while automatic Burst Mode operation maintains efficiency at light load. FEATURES ■ Tiny Solution Size ■ Low Quiescent Current: 150µA in Active Mode (VIN = 3.6V, VOUT = 15V, No Load) 1µA in Shutdown Mode ■ Internal 1A, 36V Switch ■ Integrated Schottky Diode ■ Integrated PNP Output Disconnect ■ Internal Reference Override Pin ■ PGOOD Pin ■ 25V at 80mA from 3.6V Input ■ Auxiliary NPNs for Intermediate Bias Voltages (LT3473A) ■ Automatic Burst Mode® Operation at Light Load ■ Constant Switching Frequency: 1.2MHz ■ Thermal Shutdown ■ Input Range: 2.2V to 16V ■ Low Profile (3mm × 3mm) DFN Package (LT3473) ■ Low Profile (4mm × 3mm) DFN Package (LT3473A) APPLICATIONS ■ OLED Bias ■ CCD Bias |
