Description

A1668 is -200V, -2A, Silicon PNP Power Transistor.

PNP transistors comprise the following key components:

PNP transistors control the flow of a large current (collector current) between the emitter and collector using a small current applied to the base (base current). When a base current flows, the PNP transistor permits the flow of electrons from the emitter to the collector, resulting in an increase in collector current. Reducing the base current reduces the collector current. Consequently, PNP transistors are valuable electronic components for controlling large output currents with small input currents.

PNP transistors find applications in amplifiers, switches, amplitude modulators, power amplifiers, and various circuit designs, playing a crucial role in electronic devices and circuitry.

MT7201 PDF – 1A, LED Driver with Internal Switch

Part Number: MT7201

Function: 1A, LED Driver with Internal Switch

Package: SOT89-5 Type

Manufacturer: Maxic Technology

Images:MT7201 pinout

Description

The MT7201 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 7~40V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 32 watts of output power. The MT7201 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. Output current can be adjusted above, or below the set value, by applying an external control signal to the ‘ADJ’ pin. The ADJ pin will accept either a DC voltage or a PWM waveform. Depending upon the control frequency, this will provide either a continuous or a gated output current.
