Description
The STEVAL-ISV015V1 demonstration board is a
solar harvester system designed to supply USB
devices and is based on the ST devices SPV1040
(solar voltage boost converter) and LD39050
(voltage regulator with low quiescent current and
low noise). The SPV1040 is a high efficiency, low
power and low voltage monolithic step-up
converter that operates over a 0.3 V to 5 V input
voltage range, therefore allowing the use of even
a few solar cells in all portable applications where
the capability of handling low input voltages is of
utmost importance. Despite the variation of
several conditions throughout the day (such as
irradiation, dirt, temperature, etc.) the SPV1040
allows the achievement of maximum efficiency
(90% typ.) in terms of power harvested from the
cells and transferred to the output thanks to the
embedded MPPT algorithm. The SPV1040 allows
the output voltage to be regulated by using an
external resistive divider up to 5.2 V, limiting the
current supplied to protect the battery and the
measuring of input current and voltage to
research the maximum power point through a
dedicated input pin. Furthermore, the device can
be shut off by driving an XSHUT pin to a logic
level low, in order to save power when its working
mode is not required. Self protection features like

overtemperature and overcurrent at the input are
implemented. The LD39050 provides 500 mA
maximum current from an input voltage ranging
from 1.5 V to 5.5 V with a typical dropout voltage
of 200 mV. It is available in a fixed output voltage
version from 0.8 V up to 4.5 V (100 mV steps), or
adjustable between 0.8 V and V
low drop-voltage, low quiescent current and low
noise features make it suitable for low power
battery-powered applications. Stability is ensured
using ceramic capacitors. The power supply
rejection is 65 dB at low frequencies and starts to
roll off at 10 kHz. An enable logic control function
puts the LD39050 in shut-down mode allowing a
total current consumption of lower than 1 µA. The
device also includes short-circuit constant current
limiting and thermal protection.
