LM5165YDRCR Electronic Components Parts IC Integrated Chip In Stock
The high-side P-channel MOSFET can operate at 100% duty cycle for lowest dropout voltage and does not require a bootstrap capacitor for gate drive. Also, the current limit setpoint is adjustable to optimize inductor selection for a particular output current requirement. Selectable and adjustable start-up timing options include minimum delay (no soft start), internally fixed (900 µs), and externally programmable soft start using a capacitor. An open-drain PGOOD indicator can be used for sequencing, fault reporting, and output voltage monitoring. The LM5165 buck converter is available in a 10-pin, 3-mm × 3-mm, thermally-enhanced VSON-10 package with 0.5-mm pin pitch.

Switching Regulators
1.What is Switching Regulators:
The voltage regulator is a device that makes the output voltage stable and consists of a voltage regulator circuit, a control circuit, and a servo motor. When the input voltage or load changes, the regulator control circuit samples, compares and amplifies, and then drives the servo motor to rotate so that the position of the regulator's carbon brush changes. It keeps the output voltage stable by automatically adjusting the coil turns ratio.
The switching regulator is used to generate the output voltage by controlling the transistor to switch between the ON state, and OFF state and with the energy storage components (capacitors and inductors) to keep the voltage stable. It is adjusted by adjusting the switching timing according to the feedback samples of the output voltage.
Function introduction
A voltage regulator is a kind of power supply circuit or power supply equipment that can automatically adjust the output voltage. The role of the voltage regulator is to fluctuate and not up to the requirements of electrical equipment to stabilize the power supply voltage in its set value range so that a variety of circuits or electrical equipment can work normally at the rated working voltage.
Scope of application
The voltage regulator can be widely used in industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, scientific research, and other places that need power supply voltage stability. Also adapted to electronic computers, precision machine tools, computer tomography (CT), precision instruments, test devices, lift lighting, imported equipment, production lines, and other equipment. In addition, the voltage regulator is also suitable for low or high power supply voltage, fluctuations at the end of the low-voltage distribution network of users, and load changes in power equipment. The voltage regulator is particularly suitable for all the high requirements of the grid waveform voltage stabilization of power places. High power compensating power regulators can be connected to thermal, hydraulic, and small generators.
Classification
According to the different nature of the output of the regulator, the regulator is generally divided into AC regulator (AC voltage stabilization power supply) and DC regulator (DC voltage stabilization power supply) two categories.
AC voltage regulator: voltage regulator has large tens to thousands of kilowatts of AC voltage regulator, is the supply of large experimental and industrial, medical equipment work power. There are also small AC voltage regulators of a few watts to a few kilowatts, which are for small laboratories or home appliances to provide high-quality power.
DC regulators: According to the operating state of the adjustment tube, DC regulators are often divided into two categories: ware and switching regulators. Switching regulator rectifier, smoothing circuit has a capacitor input type and choke coil input type two types, need to be flexible according to the switching regulator circuit way to use. The choke coil input type is used in step-down switching regulators, while the capacitor input type is used in step-up switching regulators.
This product is a step-down converter.
