Its 1.8 A switch current rating defines the power ceiling — actual output current depends on the input-to-output delta and efficiency, but the topology means the output stays regulated whether the battery is above or below the target rail. Switching at 2.5 MHz, the converter lets the external inductor and capacitors shrink to 0402 or 0603 footprints — important when the board area is tight around the 12-WLP (1.61 x 2.01 mm) package. No synchronous rectifier is used, so expect slightly lower efficiency at heavy loads compared to a synchronous part, but the simpler gate drive keeps quiescent current low.","metaTitle":"MAX77827BEWC+ Buck-Boost Regulator, 1.8A, 12-WLP","metaDescription":"Analog Devices MAX77827BEWC+ step-up/step-down DC-DC converter, 2.6-5.5V input, adjustable output to 5.3V, 1.8A switch, 2.5MHz, 12-WLP.

Output is adjustable from a minimum of 2.3 V up to a maximum of 5.3 V. The buck-boost topology means the output stays regulated when the input dips below or rises above the set output voltage — essential for single-cell Li-ion applications where the battery voltage swings from 4.2 V down to 3.0 V."},{"question":"Does MAX77827BEWC+ have a synchronous rectifier?","answer":"No. The MAX77827BEWC+ uses an external diode for the low-side rectification. This simplifies the design and reduces switching losses at light loads, but the efficiency at high output current will be a few points lower than a synchronous buck-boost. For loads above 1 A, factor in the diode forward drop when budgeting thermal performance."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX77827BEWC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX77827BEWC when reusing this data.
