Description
The ADP1823 is a versatile, dual, interleaved, synchronous, PWM buck controller that generates two independent output rails from an input of 3.7 V to 20 V, with a power input voltage that ranges from 1 V to 24 V.
Features
- Fixed-frequency operation: 300 kHz, 600 kHz, or synchronized operation up to 1 MHz
Supply input range: 3.7 V to 20 V Wide power stage input range: 1 V to 24 V Interleaved operation results in smaller, low cost input
capacitor All-N-channel MOSFET design for low cost ±0.85% accuracy at 0°C to 70°C Soft start, thermal overload, current-limit protection 10 μA shutdown supply current Internal linear regulator Lossless RDSON current-limit sensing Reverse current protection during soft start for handl.
