ADP1823 Step-Down DC-to-DC Controller

ADP1823 Description

Dual, Interleaved, Step-Down DC-to-DC Controller with Tracking ADP1823 .
The ADP1823 is a versatile, dual, interleaved, synchronous, PWM buck controller that generates two independent output rails from an input of 3.

ADP1823 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 So

ADP1823 Applications

* Telecommunications and networking systems Medical imaging systems Base station power Set-top boxes Printers DDR termination TYPICAL APPLICATION CIRCUIT IN = 12V 180µF 1µF PV IN EN1 TRK1 EN2 TRK2 VREG 180µF 0.47µF IRLR7807Z 1.2V, 6A 560µF 2.2µH 2kΩ 2kΩ IRFR3709Z BST2 BST1 0.47µF DH1 DH
