Product details
Overview
The MAX619ESA+ from Maxim Integrated is a regulated 5V ±4% charge-pump DC-DC converter designed for battery-powered systems requiring compact, inductorless voltage boosting. It delivers up to 50mA output current from a 2V–3.6V input (e.g., two alkaline or NiMH cells), features 500kHz internal switching, 1µA max shutdown current, and operates across –40°C to +85°C.
For engineers reviewing the MAX619ESA+ datasheet, MAX619ESA+ pinout, MAX19ESA+ application, or MAX619ESA+ equivalent, key selection criteria include guaranteed output current over temperature, ultra-low quiescent current, load-disconnect capability during shutdown, and SO-8 package compatibility with space-constrained portable designs.
Technical Context
The MAX619ESA+ implements a pulse-skipping control architecture that dynamically selects voltage-doubling (VIN ≥3.0V), voltage-tripling (VIN ≤2.5V), or 2.5× mode (2.5V < VIN < 3.0V) to maintain regulation and maximize efficiency across its 2V–3.6V input range. Internal circuitry is powered from the higher of VIN or VOUT to sustain operation at low input voltages.
It requires only four external capacitors - two 0.22µF flying caps and two 10µF bulk caps - eliminating inductors and minimizing EMI. Shutdown disconnects OUT from IN, preventing backfeed, and SHDN accepts CMOS-level logic control with ±10µA input current.
Key Specifications

|---|---|
| Output Voltage | 5.0V ±4% (4.8V–5.2V); tightly regulated without external feedback components |
| Max Output Current | 50mA @ VIN ≥3.0V; sufficient for microprocessor I/O, flash programming, and op-amp rails |
| Input Voltage Range | 2.0V to 3.6V; matches nominal voltage of two primary or rechargeable cells |
| No-Load Supply Current | 170µA max; enables multi-year battery life in always-on low-duty-cycle devices |
| Shutdown Current | 1µA max; ensures negligible drain during system sleep states |

Pinout & Package
MAX619ESA+ is housed in an 8-pin SO (Small Outline) package, 3.9mm × 4.9mm body, 1.27mm pitch, RoHS-compliant, with exposed pad optional per variant. Pin functions are electrically validated and thermally optimized for charge-pump capacitor routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1+ | Positive terminal of flying capacitor C1 | Connects to one plate of first charge-pump capacitor; critical path for energy transfer timing |
| C1− | Negative terminal of flying capacitor C1 | Reference node for C1 charging phase; tied internally to switching matrix |
| IN | Main input supply connection | Accepts 2V–3.6V source; powers internal logic and feeds charge-pump network |
| OUT | Regulated 5V output | Delivers up to 50mA; disconnected from IN during shutdown |
| C2+ | Positive terminal of flying capacitor C2 | Second flying cap node; participates in series/parallel reconfiguration per VIN level |
| C2− | Negative terminal of flying capacitor C2 | Common reference for C2; switches between GND and IN depending on pump phase |
| SHDN | Active-high shutdown control | CMOS-compatible input; pulls internal switches open when high, halting all pumping |
| GND | Analog/digital ground reference | Single ground plane required; substrate tied to this pin for thermal and noise control |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge-pump DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60110IDR | Fixed 5V output, 100mA max, 1MHz switching, requires different capacitor values (1µF flying caps) | Higher output current but larger solution size and higher EMI; not rated for –40°C operation | Select when >50mA load current is required and industrial temp range is not mandatory |
| LM2703MMX/NOPB | 5V ±5%, 60mA, 1.25MHz, no auto-mode switching; less efficient below 2.5V input | Lower quiescent current (110µA) but lacks load-disconnect; SO-8 but different pinout | Select when minimal IQ dominates design priority and shutdown isolation is handled externally |
Compared with TPS60110IDR and LM2703MMX/NOPB, the MAX619ESA+ uniquely combines guaranteed 50mA output across –40°C to +85°C, true load-disconnect during shutdown, and adaptive pump-mode selection - enabling robust, space-constrained, battery-critical designs without trade-offs in reliability or thermal margin.

FAQ
What is the guaranteed output current of the MAX619ESA+ over its full operating temperature range?
The MAX619ESA+ guarantees 20mA output current when VIN ≥2V and 50mA when VIN ≥3V across its full –40°C to +85°C operating temperature range. This is explicitly specified in the Electrical Characteristics table under "Output Current Guaranteed over Temperature" and confirmed in Typical Operating Characteristics plots showing VOUT stability up to 50mA load at TA = –40°C and +85°C.
Does the MAX619ESA+ provide load disconnection during shutdown?
Yes, the MAX619ESA+ fully disconnects the OUT pin from the IN pin during shutdown. When SHDN is driven high, internal switches open, isolating the output from the input supply. This prevents backfeed and preserves battery charge - a key feature documented in both the General Description and Detailed Description sections of the datasheet.
What external components are required for basic operation of the MAX619ESA+?
The MAX619ESA+ requires exactly four external capacitors: two 0.22µF flying capacitors (C1 and C2) connected to C1+/C1− and C2+/C2−, and two 10µF bulk capacitors (C3 at IN–GND and C4 at OUT–GND). No inductors, diodes, or resistors are needed - enabling a complete solution in under 0.1in² board area.
Is the MAX619ESA+ pin-compatible with other variants in the MAX619 family?
Yes, the MAX619ESA+ shares identical pinout and footprint with all other MAX619 variants (e.g., MAX619CPA, MAX619EPA, MAX619MJA) in DIP and SO packages. The SO-8 package used by MAX619ESA+ has standardized 1.27mm pitch and mechanical dimensions matching industry SOIC-8 standards, enabling drop-in replacement within the same package type.
What is the typical startup time for the MAX619ESA+ after exiting shutdown?
Under no-load conditions with VIN = 3.6V, the MAX619ESA+ typically reaches 5V output within 0.5ms after SHDN transitions from high to low. This value is measured and specified in the Typical Operating Characteristics section and reflects the device's fast enable response, critical for wake-from-sleep applications in portable systems.
