MAXM15465/MAXM15466/
MAXM15467
4.5V to 42V, 300mA 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 MAXM15465/MAXM15466/MAXM15467
are a family of high-efficiency, synchronous step-down
DC-DC modules with integrated controller, MOSFETs,
compensation components, and inductor that operate
over a wide input-voltage range. The modules oper-
ate from 4.5V to 42V input and deliver up to 300mA
output current. The MAXM15465 and MAXM15466
are fixed 3.3V and 5V output modules respectively.
The MAXM15467 is an adjustable output (0.9V to
6.3V) module. The modules significantly reduce design
complexity, manufacturing risks, and offer a true plug and
play power/supply solution, reducing time-to-market.
• Wide 4.5V to 42V Input
• Adjustable 0.9V to 6.3V Output
• Fixed 3.3V and 5V Output
(MAXM15465 and MAXM15466)
• ±1.5% Feedback Accuracy
• Up to 300mA 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 MAXM15465/6/7 modules employ peak-current-
mode control architecture. To reduce input inrush current,
the modules offer a fixed 3.75ms soft-start time.
● Robust Operation
The MAXM15465/6/7 modules are available in a low
profile, compact 10-pin, 2.6mm x 3mm x 1.5mm, uSLIC™
package.
• Hiccup Overcurrent Protection
• Overtemperature Protection
