ADP5020Power Management Unit for Imaging Modules | Evaluation Boards | 1 | Obsolete | The ADP5020 provides a highly integrated power solution that includes all of the power circuits necessary for a digital imaging module. It comprises two step-down dc-to-dc converters, one LDO, and a power sequence controller. All dc-to-dc converters integrate power pMOSFETs and nMOSFETs, making the system simpler and more compact and reducing the cost. The ADP5020 has digitally programmed output voltages and buck converters that can source up to 600 mA. A fixed frequency operation of 3 MHz enables the use of tiny inductors and capacitors. The buck converters use a voltage mode, constant-frequency PWM control scheme, and the synchronous rectification is implemented to reduce the power loss. The Buck 1 regulator operates at up to 93% efficiency.The ADP5020 provides high performance, reduces component count and size, and is lower in cost when compared to conventional designs.The ADP5020 runs on input voltage from 2.4 V to 5.5 V and supports one-cell lithium-ion (Li+) batteries. The high performance LDO maximizes noise suppression. The ADP5020 can be activated via an I2C®interface or through a dedicated enable input. During logic-controlled shutdown, the input is disconnected from the output source, and the part draws 1 μA typical from the input source. Other key features include undervoltage lockout to prevent deep-battery discharge and soft start to prevent input current overshoot at startup. The ADP5020 is available in a 20-lead LFCSP.APPLICATIONSDigital cameras, handsetsMobile TVs |

ADP5023Dual 3 MHz, 800mA Buck Regulator with One 300mA LDO | Evaluation Boards | 4 | Active | The ADP5023 combines two high performance buck regulators and one low dropout (LDO) regulator in a small, 24-lead 4 mm × 4 mm LFCSP to meet demanding performance and board space requirements.The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low, the buck regulators operate in PWM mode when the load current is above a predefined threshold. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM) improving the light-load efficiency.The two bucks operate out of phase to reduce the input capacitor requirement. The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5023 LDO extends the battery life of portable devices. The ADP5023 LDO maintains power supply rejection greater than 60 dB for frequencies as high as 10 kHz while operating with a low headroom voltage.Regulators in the ADP5023 are activated though dedicated enable pins. The default output voltages can be externally set in the adjustable version or factory programmable to a wide range of preset values in the fixed voltage version.ApplicationsPower for processors, ASIC, FPGAs, and RF chipsetsPortable instrumentation and medical devicesSpace constrained devices |
