Description

The OB3370NCP is a high integrated and cost effective Light Emitting Diode (LED) driver optimized for LCD monitor and LCD TV backlight application.

The OB3370N operates in voltage mode boost topology with fixed frequency to regulate the LED
current. The LED current is sensed through an external current sense resistor. The voltage across
the sensing resistor is compared with reference level of 200mV, the error is amplified to control the
pulse width of the power switch thus to regulate the current flowing the LED. […]

Description

The HS2272, HS2272C-YX is a remote control decoding ASIC paired with HS2260. Manufactured in CMOS process, it has a maximum of 12-bit three-state address pins, which can support encoding of up to 531441 (or 312) addresses. The possibility of code collisions and illegal scanning of codes to match is thus greatly reduced.

A Remote Control Decoder ASIC (Application-Specific Integrated Circuit) is a specialized electronic component designed to decode signals from remote control devices, such as infrared (IR) or radio-frequency (RF) remotes. These ASICs are commonly used in various consumer electronics, industrial applications, and other systems that require remote control functionality. […]

Features

1. Low power consumption and strong noise suppression capability

2. Up to 12-bit tri-state address pins or 6-bit data pins

3. An oscillator circuit with an external resistor

4. There are latch type and transient output type
