Part # Distributor Manufacturer Product Category Description
TC120 Microchip Technology, Inc. Microchip Technology, Inc. Not Provided . It requires only an external inductor, Schottky diode, and two capacitors to implement a step-down converter having a maximum output current of 600 mA (VIN =5V, VOUT = 3.3V). An external switching transistor (P-channel MOSFET) can be added to increase output current capability to support output loads...
TC1266 Microchip Technology, Inc. Microchip Technology, Inc. Not Provided the lower threshold the LDO is disabled, and an external P-channel MOSFET is automatically turned on, connecting the auxiliary supply input to VOUT, and ensuring an uninterrupted 3.3V output. The main supply is automatically selected if both the main and auxiliary input supplies are present...
TC1267 Microchip Technology, Inc. Microchip Technology, Inc. Not Provided threshold the LDO is disabled, and an external P-channel MOSFET is automatically turned on, connecting the auxiliary supply input to VOUT, and ensuring an uninterrupted 3.3V output. The main supply is automatically selected if both the main and auxiliary input supplies are present, and transition from...

  • Linear Voltage Regulators
    Linear voltage regulators use an active pass element (bipolar or MOSFET) to drop the input voltage down to the regulated output voltage. They operate by using a voltage-controlled source to force a fixed voltage to appear at its output terminal. Control circuitry monitors this output voltage
  • Circuit Ideas: How to parallel regulator modules for high-current supplies
    It's often necessary to connect pointof- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so forth. Fully integrated POL power modules have a built-in inductor, power MOSFET, PWM controller
  • ENERGY STAR (R) Compliant - Low Cost LED Dimming
    in a dimmer and provides a gate voltage to the series pass MOSFET. The gate drive of the series MOSFET PWMs the LEDs at their peak current rating. The NSIC2050 Constant Current Regulators provides over current and over voltage protection to the LEDs. The NSI5010 limits the power consumption of the dimmer
  • A Digital Constant Current Power LED Driver
    be operated with an external oscillator The LED current is sampled using a resistor in series circuit to provide a higher operating frequency. with the source of the MOSFET in the buck circuit and A summary of the operating parameters used for amplified using a single op amp. The LED current
