The charge-pump topology means lower conducted and radiated noise than a switching inductor at the same load, making it a fit for powering analog front-ends, sensor bias, or RF VCOs where ripple on the supply rail directly degrades signal integrity. ## Dual switching frequency — 900 kHz or 1 MHz The switching frequency is pin-selectable between 900 kHz and 1 MHz. At 1 MHz the external flying capacitors and output capacitor can be smaller (lower profile, cheaper), while 900 kHz reduces switching losses at light loads — useful when the 500 mA rating is only hit in short bursts. No synchronous rectifier is used, so the Schottky diode's forward voltage adds to the dropout — budget about 0.4 V at 500 mA. The efficiency peak sits around 200-300 mA; above that the diode conduction loss dominates. ## 10-lead DFN with exposed pad — hand-solderable The tube packaging is fine for prototype reels, but for volume production you will want the tape-and-reel variant (LTC3203EDD#TRPBF) to feed a pick-and-place.","metaTitle":"LTC3203EDD#PBF Step-Up Charge Pump, 500 mA, 10-DFN","metaDescription":"Analog Devices LTC3203EDD#PBF adjustable step-up charge pump, 500 mA output, 2.7-5.5 V input, 10-DFN (3x3 mm).

It will not drop in as a pin-compatible replacement — the pinout and control scheme differ. For a charge-pump second source, look at the Texas Instruments TPS601xx family or the Maxim MAX828 series; neither is a direct drop-in but both serve the same step-up charge-pump function."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC3203EDD~4PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC3203EDD~4PBF when reusing this data.
