Регуляторы напряжения - Импульсные регуляторы ADP1614ACPZ-1.3-R7

Импульсный повышающий DC-DC стабилизатор , регулируемый, 2.5В-5.5В (Vin), 3.6В-20В, 4А, LFCSP-10

The ADP1614ACPZ-1.3-R7 is a Step-up PWM DC-to-DC Switching Converter with an integrated power switch capable of providing an output voltage as high as 20V. It is available with a pin-adjustable current limit that is set via an external resistor with the boost switching frequency fixed to either 650kHz or 1.3MHz. Alternatively, ADP1614 is also available with fixed 3A current limit and a pin-selectable frequency. The regulator is optimal for space constrained applications, such as portable devices or thin film transistor (TFT) liquid crystal displays (LCDs). The ADP1614 operates in current-mode pulse-width modulation (PWM) with up to 94% efficiency. Adjustable soft start prevents inrush currents when the part is enabled. The PWM current-mode architecture allows excellent transient response, easy noise filtering and the use of small, cost-saving external inductors and capacitors. Other key features include under-voltage lockout (UVLO), thermal shutdown (TSD) and logic controlled enable.
