MAXM15068
7.5V to 60V, 200mA Himalaya uSLIC
Step-Down Power Module
General Description
Benefits and Features
● Easy to Use
The Himalaya series of voltage regulator ICs and power
modules enable cooler, smaller, and simpler power-
supply solutions. The MAXM15068 is a high-efficiency,
synchronous step-down DC-DC module with integrated
controller, MOSFETs, compensation components, and
inductor that operates over a wide input-voltage range.
The module operates from 7.5V to 60V input and delivers
up to 200mA output current over a programmable output
voltage from 5V to 12V. The module significantly reduces
design complexity, manufacturing risks, and offers a true
plug and play power/supply solution, reducing time-to-
market.
• Wide 7.5V to 60V Input Range
• Adjustable 5V to 12V Output
• ±1.44% Feedback Accuracy
• Up to 200mA Output-Current
• Internally Compensated
• All Ceramic Capacitors
● High Efficiency
• Selectable PWM- or PFM-Mode of Operation
• Shutdown Current as Low as 2.2μA (typ)
● Flexible Design
• Internal Soft-Start and Prebias Startup
• Open-Drain Power Good Output (RESET Pin)
• Programmable EN/UVLO Threshold
The MAXM15068 employs peak-current-mode control
architecture. To reduce input inrush current, the device
offers a fixed 3.75ms soft-start time.
