MAXIM MAX1652 MAX1655 High-Efficiency PWM Step-Down DC-DC Controllers in 16-Pin QSOP handbook
The Maxim MAX1652‑MAX1655 family provides high‑efficiency PWM step‑down DC‑DC controllers in compact 16‑pin QSOP and narrow‑SO packages. They support input voltages from 4.5 V to 30 V and deliver up to 10 A with efficiencies as high as 96 %.
Key features include selectable 150 kHz/300 kHz switching frequencies (or external sync), dual N‑channel synchronous‑rectified control, low‑quiescent current (170 µA), and optional secondary output pins for positive or negative voltages.
