कंपनी ब्लॉग के बारे में Leadcore LC1160 Power Management System Chip: Designed for 2G/3G/4G Smartphones

Shenzhen Mingjiada Electronics Co., Ltd. has the Leadcore LC1160 power management system chip in stock: a high-performance integrated audio and power management solution designed for 2G/3G/4G smartphones. These are genuine, original products, and we support both sample and bulk deliveries.

LC1160 Product Overview

In today’s market, where smartphones and portable devices increasingly demand high integration, low power consumption and exceptional audio quality, the design of power management and audio subsystems has become a key factor influencing the user experience. The LC1160, launched by Leadcore, is a Power Management System-on-Chip (PMSoC) specifically optimised for audio applications in 2G/3G/4G mobile phones and smartphones, highly integrating a complex Power Management Unit (PMU) with a high-quality audio codec onto a single chip.

The LC1160 is commonly found in Leadcore’s LC1860 platform solutions and is widely used in devices such as smartphones, drones and portable terminals.

Core Architecture: Dual-core Integration of Power Management and Audio Subsystems

Powerful Power Management Unit (PMU)

The LC1160 incorporates nine buck converters and 26 LDOs (low-dropout linear regulators), providing comprehensive, stable and efficient multi-rail power supply to various functional modules such as the mobile phone baseband, RF, memory, display and camera. This highly integrated power management solution significantly reduces the number of external discrete components, simplifies PCB layout and frees up valuable space for compact mobile device designs.

Furthermore, the LC1160’s battery charging management system supports lithium-ion batteries, incorporates a pre-charge indication function, accepts charger input voltages of up to 15V and is compatible with USB charging, ensuring convenience and safety for the day-to-day use of mobile devices.

High-Performance Audio Subsystem

The audio section of the LC1160 is specifically designed for mobile applications that demand a high-quality audio experience, integrating a rich array of analogue and digital audio functional modules:

High-quality stereo DAC and ADC: The stereo DAC path achieves a signal-to-noise ratio (SNR) of up to 93 dB at 24-bit/48 kHz input, ensuring high-fidelity music playback and audio reproduction.

Flexible Output Drivers: An integrated stereo headphone amplifier supports both OCL (capacitorless output) and SE (AC-coupled) operating modes; it also features a single-ended receiver amplifier and a Class D speaker amplifier, the latter capable of delivering up to 800 mW of output power to an 8 Ω load at SPKVDD = 4.2 V.

Comprehensive digital audio interfaces: Features bidirectional I²S, bidirectional PCM and PDM interfaces, enabling flexible integration with external audio devices such as digital microphones and Bluetooth audio codecs to meet the diverse requirements of scenarios including voice calls, recording and AI speech recognition.

Advanced DSP processing cores

The chip integrates three DSP processing cores, responsible for internal unit configuration, communication protocol processing and audio data processing respectively. This enhances system response efficiency whilst effectively reducing the load on the main SoC.
