The ADP1870?/ ADP1871 are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current-limit, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by utilizing valley current-mode control architecture. This allows the ADP1870 / ADP1871 to drive all N-channel power stages to regulate output voltages as low as 0.6 V.The ADP1871 is the power saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads (see the Power Saving Mode (PSM) Version (ADP1871) section for more information).Available in three frequency options (300 kHz, 600 kHz, and 1.0 MHz, plus the PSM option), the ADP1870 / ADP1871 are well suited for a wide range of applications that require a single-input power supply range from 2.95 V to 20 V. Low voltage biasing is supplied via a 5 V internal LDO.In addition, an internally fixed soft start period is included to limit input in-rush current from the input supply during startup and to provide reverse current protection during soft start for a precharged output. The low-side current-sense, current-gain scheme and integration of a boost diode, along with the PSM/forced pulse-width modulation (PWM) option, reduce the external part count and improve efficiency.The ADP1870/ADP1871 operate over the -40?C to +125?C junction temperature range and are available in 10-lead MSOP package.APPLICATIONS Telecom and networking systems Mid to high end servers Set-top boxes DSP core power supplies 12 V input POL supplies

Demonstration circuit DC2527A-A features the LTM4662EY, a dual 15A or single 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 4.5V to 20V. With CPWR bias, input voltage can be as low as 2.375V. The output voltage range is 0.6V to 5.5V. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC2527A-A offers the TRACK/SS pin allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper can select discontinuous conduction mode. MODE_PLLIN pin also allows the LTM4662 to synchronize to an external clock signal (between 250kHz and 1MHz). DC2527A-A has the option of choosing both internal and external compensation circuit for LTM4662. Tying the PHASMD pin to different pins generates certain phases of CLKOUT and Channel 2. The LTM4662 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2527A-A.
