As an important partner of Microchip's brand, the company supplies a portfolio of linear voltage regulators (LDO) and switching voltage regulators covering industrial, communications, consumer electronics and other fields.


Core supply of products

1, Linear Voltage regulator (LDO)

LDO (Low Dropout Voltage Regulator) is a linear regulator that produces a regulated output voltage by subtracting excess voltage from the applied input voltage via a transistor or FET operating within its linear region. Its internal structure mainly includes regulating tube, error amplifier and reference voltage source. When the output voltage deviates from the reference voltage, the error amplifier adjusts the conduction of the regulator tube to keep the output voltage stable ‌.

Features and Application scenarios ‌ :

Low noise ‌ : The ripple of LDO is small, generally below 30mV, suitable for noise-sensitive applications.

Low power consumption ‌ : low static power consumption, suitable for low-power scenarios.

The peripheral circuit is simple ‌ : usually only need input and output capacitance, electromagnetic interference is small.

Heat dissipation problem ‌ : because the excess energy is dissipated in the form of heat, it is necessary to pay attention to the heat dissipation problem ‌.


2, switch regulator

Switching regulators (such as DCDC converters) convert voltage through inductors, capacitors, and switching tubes (such as MOSFETs or IGBTs). It can work in different modes such as boost, buck or voltage reversal, and realizes voltage conversion by controlling the on and off time of the switching tube ‌.

Features and Application scenarios ‌ :

High efficiency ‌ : Through the work of the switching tube, the energy conversion efficiency is high, suitable for the scene requiring efficient energy conversion.

High ripple ‌ : Although the ripple is large, it can be improved by filtering circuits.

Wide application range ‌ : Suitable for scenarios requiring efficient energy conversion and high power requirements ‌.


Service advantage

Product diversity ‌ : covering standard PMIC, LDO, DC-DC and other categories to meet different voltage and current needs ‌. ‌

Fast response ‌ : Relying on global branches such as Hong Kong and Japan, sample delivery and technical support within 48 hours ‌.


By integrating Microchip's high-performance products, Mingarda continues to help customers meet technical challenges in the fields of the Internet of Things and new energy ‌. More product information is available at www.hkmjd.com.
