Product details
Overview
MAX606EUA+ from Maxim Integrated is a low-profile, CMOS step-up DC-DC converter optimized for flash memory and PCMCIA card applications. It operates from 3V to 5.5V input, delivers up to 180mA at 5V (±4% output accuracy), switches at up to 1MHz, and fits in 0.25in² with height under 1.35mm - compliant with Type 1–3 card standards.
For engineers reviewing the MAX606EUA+ datasheet, MAX606EUA+ pinout, MAX606EUA+ application, or MAX606EUA+ equivalent, key selection criteria include its 1MHz switching frequency, µMAX-8 package footprint, 5V/12V/pin-programmable output, soft-start control via SS pin, and shutdown quiescent current of 0.01µA.
Technical Context
The MAX606EUA+ employs a current-limited pulse-frequency modulation (PFM) control scheme that dynamically adjusts on-time (tON = K/VIN, K = 3µs·V typical) and off-time based on input/output voltage conditions. This enables high efficiency across wide load and voltage ranges while maintaining ±4% regulation accuracy.
It integrates an internal 1Ω n-channel power MOSFET (LX pin), uses FB pin for output voltage selection (5V when tied to IN, 12V to GND, or adjustable via external divider), and features logic-controlled shutdown (SHDN active-low) with 1µA input current and user-configurable soft-start via external capacitor on SS pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports single-cell Li-ion, 3.3V/5V system rails without external LDO pre-regulation. |
| Output Voltage | Preset 5V (±4%) or 12V (±4%), or adjustable from VIN to 12.5V - configured via FB pin connection or external resistor divider. |
| Max Output Current | 180mA at 5V output - sufficient for PCMCIA slot programming and flash memory write cycles. |
| Switching Frequency | Up to 1MHz - enables use of ultra-small 5µH inductor and 0.68µF ceramic capacitors, minimizing board area. |
| Shutdown Quiescent Current | 0.01µA - extends battery life in portable memory cards during standby or sleep modes. |
| Package | 8-pin µMAX (1.11mm max height, 3mm × 3mm footprint) - half the area of standard SO-8, compliant with Type 1 PCMCIA height limit. |
| FB Regulation Setpoint | 2.00V (±2%) - sets output via VOUT = 2V × (R1/R2 + 1); enables precise adjustable outputs with minimal external components. |
Pinout & Package
MAX606EUA+ is housed in an 8-pin µMAX package (3mm × 3mm, 1.11mm max height), designed for ultra-low-profile applications including Type 1 PCMCIA and flash memory cards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - PGND | Power Ground | Return path for internal n-channel MOSFET source; must be connected to low-impedance ground plane to minimize switching noise. |
| 2 - FB | Feedback Input | Configures output: tie to IN for 5V, GND for 12V, or external divider for adjustable output (VREF = 2.00V). |
| 3 - SHDN | Shutdown Control | Active-low logic input; connect to GND for 0.01µA shutdown, to IN for normal operation; initiates soft-start on wake-up. |
| 4 - IN | Supply Input | Main power input (3.0V–5.5V); also supplies internal reference and logic; requires local 0.1µF bypass capacitor. |
| 5 - GND | Analog Ground | Reference for error amplifier and internal circuitry; separate from PGND but tied at single point near device. |
| 6 - PGND | Power Ground | Duplicate PGND pin (pin 1) - both must be soldered to ground plane to reduce thermal resistance and EMI. |
| 7 - OUT | Regulated Output | Boosted output node; connect directly to load and output filter capacitors (e.g., two 0.68µF ceramics in parallel). |
| 8 - LX | Switch Node | Drain of internal n-channel MOSFET; connects externally to inductor and Schottky diode anode; high dV/dt node requiring tight layout. |
Key Features
| Feature | Design Value |
|---|---|
| Lowest-height boost solution | Entire circuit fits ≤1.35mm height - meets strict Type 1 PCMCIA mechanical envelope requirements. |
| Pin-programmable output | 5V or 12V selected by FB pin connection - eliminates need for external feedback resistors in fixed-output designs. |
| User-controlled soft-start | SS pin accepts external capacitor to ramp current limit - reduces inrush into large output capacitance or weak batteries. |
| Ultra-low shutdown current | 0.01µA typical - preserves battery charge in memory cards during long idle periods between programming cycles. |
| Integrated 1Ω power switch | Eliminates external MOSFET - simplifies BOM and layout while enabling compact 0.25in² total solution size. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX607EUA+ | 500kHz max switching frequency, 10µH inductor, 2.5mm height, lower no-load supply current (500µA vs. 700µA typ) | Better suited for Type 2/3 cards and handhelds where height >1.35mm is acceptable and board area is more constrained than height | Select MAX607EUA+ when 1MHz switching is unnecessary and lower quiescent current at light loads is prioritized over minimum profile. |
| TPS61040DBVR | Fixed 28V output or adjustable (1.8V–28V), 500kHz switching, 600mA IOUT, SOT-23-5 package, no soft-start pin | Higher output voltage range and current capability, but lacks pin-programmable 5V/12V mode and dedicated SS control | Choose TPS61040DBVR for applications needing >12.5V output or higher load current, accepting trade-offs in footprint flexibility and soft-start configurability. |
Compared with MAX607EUA+, MAX606EUA+ offers superior height compliance and faster transient response due to higher switching frequency; compared with TPS61040DBVR, it provides tighter mechanical integration for PCMCIA cards and simpler 5V/12V selection without external resistors.

FAQ
What output voltages does the MAX606EUA+ support?
The MAX606EUA+ supports three output configurations: 5V (±4%) when FB is connected to IN, 12V (±4%) when FB is connected to GND, or an adjustable output from VIN to 12.5V using an external resistor divider on the FB pin. The internal reference is precisely 2.00V, enabling accurate custom outputs. All configurations are validated across the full -40°C to +85°C operating temperature range for MAX606EUA+.
How does the soft-start function work on the MAX606EUA+?
The MAX606EUA+ implements soft-start via the SS pin, which accepts an external capacitor to control the ramp rate of the internal current limit during power-up or wake-from-shutdown. Charging occurs through a 45kΩ internal pull-up to the 2V reference; larger capacitors increase startup delay and reduce inrush. The SS capacitor discharges fully during shutdown, ensuring repeatable behavior. This feature is especially valuable in battery-powered flash programming where limited source impedance could otherwise cause brownout.
What is the maximum output current capability of the MAX606EUA+?
The MAX606EUA+ delivers up to 180mA at 5V output (with 3.3V input) and up to 90mA at 12V output (with 5V input), as confirmed by electrical characteristics tables and typical operating curves. Performance depends on input voltage, output voltage, inductor value (5µH recommended), and thermal conditions. Derating applies above +70°C ambient; the µMAX package has a 330mW power dissipation limit at +70°C with 4.10mW/°C derating above that temperature.
Can the MAX606EUA+ be used in Type 1 PCMCIA cards?
Yes - the MAX606EUA+ is explicitly designed for Type 1 PCMCIA compliance. Its 8-pin µMAX package measures 3mm × 3mm with a maximum height of 1.11mm, and the complete circuit (including 5µH inductor and 0.68µF capacitors) occupies ≤0.25in² and remains under 1.35mm total height. This meets the strictest mechanical envelope defined by the PCMCIA standard for the thinnest card type, making MAX606EUA+ a purpose-built solution for this application.
What is the shutdown current specification for the MAX606EUA+?
The MAX606EUA+ specifies a typical shutdown quiescent current of 0.01µA (10nA) at -40°C to +85°C, with a maximum of 0.7µA over temperature. This ultra-low value is achieved by disabling the internal reference and discharging the soft-start capacitor when SHDN is pulled low. It enables multi-year battery life in infrequently powered applications such as removable memory cards, where the device spends most time in shutdown between programming events.
