650kHz/1.3 MHz, 4 A, Step-Up,PWM, DC-to-DC Switching Converter
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 undervoltage lockout (UVLO), thermal shutdown (TSD), and logic controlled enable.
The ADP1614 is available in Pb-free, 10-lead lead frame chip scale package (LFCSP).Applications
- TFT LCD bias supplies
- Portable applications
- Industrial/instrumentation equipment
