Linear Technology LT3473
The LT3473 does not include these NPNs and is offered in an 8-lead (3mm × 3mm) package. The rugged 36V switch and output disconnect circuitry allow outputs up to 34V to be easily generated in a simple boost topology.| Part No. | LT3473 |

● 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) 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.
