MAXM38643 Tiny, 1.8V to 5.5V Input, 330nA I<sub>Q</sub>, 600mA nanoPower Buck Module

MAXM38643 Tiny, 1.8V to 5.5V Input, 330nA IQ, 600mA nanoPower Buck Module

The MAXM38643 is an ultra-low-IQ (330nA) buck module that steps down input voltages in the range of 1.8V to 5.5V to a wide range of output voltages between 0.7V to 3.3V (using a single resistor at the RSEL pin). The output voltage is programmable upon startup using a single external resistor from the RSEL pin to GND. Factory-preprogrammed fixed output voltage versions from 0.5V to 5V are also available that do not use the RSEL pin to set the output voltage. In this case, the RSEL pin in the module is left floating.

The module offers robust performance features. To optimize efficiency and transient response across the load operation range, the module automatically switches between ultra-low-power mode (ULPM), low-power mode (LPM), and highpower mode (HPM) to better service the load, depending on the load current. The device overregulates in ULPM to improve efficiency and allow the output capacitor to handle the transient load currents. The device has 90% duty cycle limitation. An active discharge resistor pulls OUT to ground when the part is in shutdown.

MAXM17225 Tiny, 0.4V to 5.5V Input, 300nA I<sub>Q</sub>, nanoPower Boost Module with True Shutdown

MAXM17225 Tiny, 0.4V to 5.5V Input, 300nA IQ, nanoPower Boost Module with True Shutdown

The MAXM17225 is a nanoPower, ultra-low-IQ (300nA) boost module offered in a tiny eMGA package. The IC is guaranteed to startup with voltages as low as 0.88V and post startup, the input voltage VIN can go down to 0.4V making it ideal for battery-operated devices that undergo voltage discharge over time. Its ultra-low quiescent current of 300nA prolongs battery life and extends product lifetime as well. The IC accepts input voltage from 0.4V to 5.5V and boosts it up to programmable output voltages from 1.8V to 5V. The output voltage is set using a single external resistor (RSEL). The product has a maximum efficiency of 95%. The module is well suited for a host of applications like battery-operated devices, portable electronics where step-up conversion is needed in space constrained enclosures while demanding high efficiency. A true shutdown disconnects the input from the output, conserving battery life. The IC has an integrated 1µH inductor chosen for optimized operation, stability, and efficiency. Guaranteed Boost VOUT regulation for 250mV separation between input and output voltages while driving heavy loads. A single external selectable resistor (RSEL) for VOUT setting reduces quiescent current consumption in comparison with a conventional resistor feedback divider string. The MAXM17225 has a fixed maximum 300ns switch turn-on time and peak inductor current limit of 1A. The IC auto-transitions between the ULPM, LPM, and HP operating modes based on load current, enabling better system transient response and efficiency. All these powerful features are packed in a tiny 10-lead eMGA package offering the end designer an efficient tool to design products.

MAXM17575 4.5V to 60V, 1.5A High-Efficiency, DC-DC Step-Down Power Module with Integrated Inductor

MAXM17575 4.5V to 60V, 1.5A High-Efficiency, DC-DC Step-Down Power Module with Integrated Inductor

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17575 is an easy-to-use power module that combines a synchronous step-down DC-DC converter, a fully shielded inductor, and compensation components into a low-profile, thermally-efficient, system-in-package (SiP). The device operates over a wide input-voltage range of 4.5V to 60V, delivers up to 1.5A continuous output current and has excellent line and load regulation over an output-voltage range of 0.9V to 12V. The high level of integration significantly reduces design complexity, manufacturing risks, and offers a true plug-and-play power-supply solution, reducing time-to-market.

The MAXM17575 offers resistor-programmable switching frequency, active-low RESET output-voltage monitoring, adjustable input undervoltage lockout, and programmable soft-start. The device also features hiccup-mode overload protection, and thermal shutdown function.

The MAXM17575 is available in a low-profile, highly thermal-emissive, compact, 28-pin 6.5mm × 10mm × 2.92mm SiP package, which reduces power dissipation and enhances efficiency. The package is easily soldered onto a printed circuit board and is suitable for automated circuit board assembly. The device can operate over the industrial temperature range from -40°C to +125°C.
