The FRDMCD1020EVM Evaluation Board (EVB) features the CD1020, a 22-channel switch detection interface with a programmable wetting current.
TIDA-00779 is a 3.5kw affordable power factor regulator converter designed for room air conditioners and other large appliances. This reference design is a continuous conduction mode (CCM) boost converter and is implemented using the TI UCC28180 PFC controller and all the necessary built-in protection mechanisms that come with it. The hardware design has been tested and passed IEC61000 surge and EFT test requirements for household appliances.
This power module generates all the voltages required to power the Class D audio amplifier. The main output voltage is 36V, which provides 200W of continuous power and 540W of peak power. The first stage is a power factor correction boost. The flyback converter provides 12V on the primary side and 12V (300mA) and 3.3V (200mA) on the secondary side. Using a hardware switch and remote input, the converter can enter standby mode: in this state, the 36V output is disabled and 12V, 3.3V are "always on". In this way, the standby power can be reduced to 150mW (115Vac) and 270mW (230Vac). A second digital input switches the main input voltage from 36V to 18V, allowing it to enter a low-current consumption mode when the audio amplifier requires less power.
The PMP10595 reference design is a miniature 1.8V 2A output power supply using the SIMPLE SWITCHER® LMZ20502 micro module. This reference design leverages the LMZ20502's tiny package and high level of integration to achieve a small solution size of approximately 5mm x 6mm (30 mm2). This design has an input voltage range of 2.7V to 5.5V and provides an output of up to 2A. On the reference board, the LMZ20502 is set to automatic mode to achieve high efficiency at light load and full load.
