DESCRIPTION
This highly integrated PWM controller provides several
features to enhance the performance of low-power
flyback converters. The patented topology of SGP100
enables simplified circuit design for battery charger
applications. The result is a low-cost, smaller and lighter
charger than a conventional design or a linear transformer.
To minimize the standby power consumption, the
proprietary green-mode function provides off-time
modulation to linearly decrease PWM frequency under
light-load conditions. This green-mode function allows
the power supply to meet power conservation
requirements. The start-up current is only 10μA, which
allows large start-up resistance for further power saving.
A charger can be implemented with few external
components and minimal cost. A typical output CV/CC
characteristic envelope is shown in Figure 1.
