Beschreibung

KI-Übersetzung

The LTC1430A is a high power, high efficiency switching regulator controller optimized for 5V to 1.xV - 3.xV applications. It includes a precision internal reference and an internal feedback system that can provide output regulation of ±1% over temperature, load current and line voltage shifts. The LTC1430A uses a synchronous switching architecture with two N - channel output devices, eliminating the need for a high power, high cost P - channel device. Additionally, it senses output current across the drain - source resistance of the upper N - channel FET, providing an adjustable current limit without an external low value sense resistor. The LTC1430A includes a fixed frequency PWM oscillator for low output ripple under virtually all operating conditions. The 200kHz free - running clock frequency can be externally adjusted from 100kHz to above 500kHz. The LTC1430A’s maximum duty cycle is typically 93.5% compared to 88% for the LTC1430. This permits 3.3V to 2.XV conversion using a low power 5V supply. The LTC1430A features low 350μA quiescent current, allowing greater than 90% efficiency operation in converter designs from 1A to greater than 50A output current. Shutdown mode drops the LTC1430A supply current to 1μA.
