STOD1317B

170 mA 13 V, high efficiency

boost converter + LDO

Datasheet - production data

Description

The STOD1317B is a fixed frequency, high

efficiency, boost DC-DC converter with cascaded

LDO able to provide output voltages ranging from

6 V to 13 V starting with an input voltage from

2.6 V to 4.8 V. The device is designed to supply

loads that are very sensitive to output ripple such

as AMOLED display panels. A dedicated LDO is

able to suppress any ripple and noise coming out

from the DC-DC converter. The LDO works with a

constant drop in order to maintain high efficiency

DFN12L (3 x 3 mm)

in the whole operating range. The low R

N-

DSon

channel and P-channel MOSFET switches are

integrated and contribute to achieving high

efficiency. The true-shutdown feature allows

physical disconnection of the battery from the

load when the device is in shutdown mode. The

control technique is able to maintain efficiency

higher than 85% at light loads and higher than

80% at full load. The device includes soft-start

control, inrush current limiter, thermal shutdown

and inductor peak current limit. The STOD1317B

is packaged in DFN12L (3 x 3 x 0.8 mm) height.
