Description

This is Solar Lawn Controller. YX805A is a stable performance solar lawn lamp boost control chip, suitable for a 1.25V battery powered solar lawn lamp.

The main functions are charge control, boost drive, light control, low voltage protection, etc. Solar lawn lights mainly use the energy of solar cells to work, when the sun shines on the solar cells during the day On the pool, the light energy is converted into electrical energy and stored in the battery, and then the battery provides power for the LED (light-emitting diode) of the lawn lamp at night. Its advantages are mainly safety, energy saving, convenience, and environmental protection.

Features:

1. High efficiency: 80~90% (typical value), can make full use of solar cells

2. Few external components: an inductor

3. Low-voltage battery protection function

4. The input current can be adjusted by adjusting the capacitance

[…]

Applications:

1. Solar Lawn Light

2. Solar string lights

3. LED driver

A CRM PFC (Continuous Conduction Mode Power Factor Correction) Controller is an electronic device used in power supply circuits to improve power factor and overall energy efficiency. Power factor correction is important because it helps reduce the distortion of the AC current waveform and improves the utilization of electrical power, especially in applications with non-linear loads.

Description

The MAP8802 is an active power factor correction (PFC) controller for boost PFC applications that operates in critical conduction mode (CRM) In CRM operation, the on time is constant during the ac line cycle and the off time varies with the instantaneous input voltage.

The voltage mode CRM PFC controller does not need the input voltage sense line. It can reduce power loss. CRM operation is an ideal choice for medium power (100W~300W) PFC boost stages with the zero current switching of DCM operation […]
