LT1976HFE#PBF is a DC DC switching regulator for use in portable electronic devices. It offers a high efficiency and low noise profile with a wide input voltage range. The device is designed to deliver high efficiency power at high frequencies with minimal external components.

In DC-DC switching voltage regulators, a switching element - such as a MOSFET, IGBT or BJT - is used to vary the input voltage, thereby regulating the output voltage. The LT1976HFE#PBF is designed to deliver low noise and a wide input voltage range with minimal external components. The frequency of theLT1976HFE#PBF can be set with its frequency control pin set to a wide range. This control range allows fast dynamic response and standby current savings. The LT1976HFE#PBF also offers additional protection features such as output undervoltage, overvoltage, and overcurrent protection.

The LT1976HFE#PBF can be used in a variety of applications such as cellular phones, PDAs, MP3/CD players, digital video cameras, and other portable devices. The LT1976HFE#PBF is capable of providing up to 500mA output current, and can deliver up to 15V output voltage. This device is suitable for design applications that require low noise, high efficiency, and very small size.

The LT1976HFE#PBF offers a wide input voltage range from 6V to 20V and can supply up to 500mA output current. The device is optimized for low noise performance and has a frequency range from 350kHz to 1MHz with a high efficiency of up to 95%. The device also has a wide input regulation range of 0.3V to 10V guaranteeing output voltage accuracy even under varying input voltage conditions. The LT1976HFE#PBF also contains over-voltage, over-current and under-voltage protection circuitry for added protection.

The LT1976HFE#PBF is designed to be used with very few external components such as inductors, capacitors, and MOSFETs. The device requires only two external components, an inductor and a capacitor. The LT1976HFE#PBF can be easily configured to be used as either Constant Voltage Output (CVO) or Constant Current Output (CCO) regulator. The device is pin-compatible with other applications that accept the same type and footprint.

The LT1976HFE#PBF has low start-up current, low quiescent current and very low EMI and RFI emissions for a quiet operation with minimal distortion. The device also has an integrated soft-start control, making it ideal for LED applications, and is able to switch from a no-load condition to a full load condition without any external current limiting. The device is RoHS compliant and comes in a 5-lead SOT-23 package with a 1.0mmx1.5mm footprint.
