Description

General part information

ADP1876 Series

The ADP1876 is a dual output dc-to-dc synchronous buck controller operating at 600 kHz fixed frequency with integrated drivers that drive N-channel power MOSFETs. An additional fixed voltage output, 150 mA linear regulator is available for powering low power loads. The device operates in current mode for improved transient response and uses valley current sensing for enhanced noise immunity. The two PWM outputs are phase shifted 180° for reducing the input current ripple and the required input capacitance.The ADP1876 provides high speed, high peak current drive capability with dead time optimization to enable energy efficient power conversion.Additional flexibility is provided by external programmability of loop compensation, soft start, current limit and current sense gain can all be programmed using external components. The ADP1876 has integrated boost diodes and power good. Protection features include under-voltage lock-out, over-current/short-circuit and over temperature. The ADP1876 provides an output voltage accuracy of ±0.85% from −40°C to +85°C and ±1.5% from −40°C to 125°C in junction temperature. This part can be powered from a 2.75 V to 20 V supply, operates over the −40°C to +125°C junction temperature range, and is available in a 32-lead 5 mm × 5 mm LFCSP package.ApplicationsConsumer applicationsTelecommunications base station and networkingIndustrial and instrumentation
