The ADPL12002/ADPL12003 ICs are small, synchronous buck converters with integrated high-side and low-side switches. The ICs are designed to deliver up to 2.5A/3.5A with a wide, 3V to 20V input voltage range. Voltage quality can be monitored by observing the PGOOD signal. The ICs can operate in dropout mode by running at a 99% duty cycle, making it ideal for factory automation applications.
The ADPL12002/ADPL12003 ICs offer externally programmable output voltage. Fixed internal frequency options of 400kHz/1.5MHz are available, allowing for small external components and reduced output ripple.
When SYNC is low, the ADPL12002/ADPL12003 automatically enters skip mode at light loads with an ultra-low quiescent current of 27μA at no load. A pin-selectable Forced–Pulse-width modulation (PWM) mode is also available, which helps to improve Electromagnetic Interference (EMI) performance. The devices have a spread-spectrum frequency modulation option designed to minimize EMI-radiated emissions due to the modulation frequency.
The ADPL12002/ADPL12003 ICs are available in a small, 3mm x 3mm, 17-pin flip-chip quad flat no-lead (FC2QFN) package, utilizing a few external components.
