Product details
Overview
NCP1410DMR2G from onsemi is a monolithic, micropower, synchronous rectified PFM step-up DC-DC converter IC designed for battery-powered handheld electronics. It delivers up to 250 mA output current at 3.3 V from a 2.5 V input, integrates an internal N- and P-channel MOSFET pair, operates with 9.0 µA typical quiescent supply current, and features a 1.19 V ±0.6% reference voltage and open-drain low-battery detector output - enabling compact, high-efficiency power conversion in single- or dual-cell NiMH/NiCd or Li-ion systems.
For engineers reviewing the NCP1410DMR2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 600 kHz switching frequency for small-inductor designs, cycle-by-cycle 1.0 A current limit, logic-controlled shutdown (0.05 µA shutdown current), Micro8 package footprint, and integrated synchronous rectification eliminating external Schottky diodes.
Technical Context
The NCP1410DMR2G uses a pulse-frequency modulation (PFM) control scheme with fixed maximum ON-time (1.4 µs typical) and minimum OFF-time (0.31 µs typical) to regulate output voltage via feedback to the FB pin. Its internal voltage reference (1.19 V) sets both output regulation and low-battery detection thresholds through external resistor dividers.
Synchronous rectification is implemented using integrated N-FET (RDS(ON) = 0.6 Ω) and P-FET (RDS(ON) = 0.9 Ω) switches with dead-time control to prevent shoot-through; a zero-current detector (ZLC) ensures M2 turns off before reverse inductor current flows in DCM operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | Up to 250 mA at VIN = 2.5 V, VOUT = 3.3 V - supports mid-power portable loads without external pass devices. |
| Quiescent Supply Current | 9.0 µA typical - enables >1-year battery life in always-on low-power monitoring circuits. |
| Switching Frequency | Up to 600 kHz - permits use of 22 µH low-profile inductors and ceramic output capacitors ≤33 µF. |
| Reference Voltage | 1.190 V ±0.6% at 25°C - provides stable feedback and low-battery threshold with <0.03 mV/°C drift. |
| Current Limit | 1.0 A cycle-by-cycle - protects internal FETs and external inductor during startup or overload without external sensing. |
| Startup Input Voltage | 1.0 V guaranteed at no load - supports operation down to near-dead alkaline or NiMH cells. |
| Shutdown Current | 0.05 µA typical - reduces system standby drain to negligible levels in battery-critical applications. |
Pinout & Package
The NCP1410DMR2G is housed in a Pb-free Micro8 (Case 846A) surface-mount package measuring 3.0 mm × 3.0 mm × 1.1 mm, with 0.65 mm lead pitch and exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FB | Feedback input | Connects to resistor divider from VOUT; regulates output by comparing divided voltage to 1.19 V internal reference. |
| 2 - LBI | Low-battery sense input | High-impedance input for resistor divider from battery; triggers LBO when voltage drops below 1.178 V. |
| 3 - LBO | Open-drain low-battery output | Sinks current when LBI < 1.178 V; requires external pull-up for system-level battery alert signaling. |
| 4 - REF | Precision reference output | Supplies 1.19 V ±0.6%; can drive ≥2.5 mA load at VOUT ≥ 3.3 V with 1.0 µF bypass capacitor. |
| 5 - SHDN | Logic-controlled enable input | Active-high (≥0.6 V) enables operation; <0.3 V forces shutdown with <0.05 µA supply current. |
| 6 - GND | Power and signal ground | Common return for all internal circuitry and external components; must be star-connected per layout guidelines. |
| 7 - LX | Switch node | Drain connection of internal N-FET and P-FET; connects to inductor and optional startup Schottky diode anode. |
| 8 - OUT | Power output | Delivers regulated output; supplies bootstrap power to internal circuitry and drives external output capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated synchronous rectifier | Eliminates external Schottky diode, reducing BOM count and conduction losses - enables 92% peak efficiency at 100 mA. |
| Micro8 package | 3.0 × 3.0 mm footprint with 0.65 mm pitch - fits space-constrained PDA, camera, and handheld instrument PCBs. |
| Low-battery detector with hysteresis | 30 mV hysteresis prevents chatter near threshold; open-drain LBO allows flexible interface with microcontroller GPIO or LED drivers. |
| PFM control with adaptive timing | Variable frequency operation maintains high light-load efficiency; fixed tON/tOFF ensures stability across input/output ranges. |
| 1.0 V no-load startup | Enables reliable boot from deeply discharged cells (e.g., 1× alkaline at end-of-life), critical for consumer remote controls and sensors. |

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 |
|---|---|---|---|
| TPS61022DRVR | Higher 2.0 A current limit; 2.5 V to 5.5 V input; 93% peak efficiency; requires external compensation. | Supports higher output currents (up to 1.2 A) and wider input range - better suited for USB-powered accessories. | Select TPS61022DRVR when >250 mA output or >5.5 V output is required; NCP1410DMR2G remains optimal for ultra-low-IQ battery longevity. |

FAQ
What is the minimum input voltage required for NCP1410DMR2G to start up?
The NCP1410DMR2G guarantees startup at 1.0 V with no load, as confirmed in the Electrical Characteristics table (Section 3). This enables reliable operation from nearly depleted alkaline or NiMH cells. Under load, startup voltage increases slightly depending on output current and inductor value - e.g., ~1.2 V at 100 mA output with a 22 µH inductor. The device's PFM architecture and low 9.0 µA quiescent current ensure robust low-voltage functionality not achievable with standard PWM boost controllers.
Does NCP1410DMR2G require an external Schottky diode?
No - the NCP1410DMR2G integrates synchronous rectification using internal N- and P-channel MOSFETs, eliminating the need for an external Schottky diode in normal operation. However, the datasheet recommends adding an optional MBR0502 Schottky diode between LX and OUT pins only when starting from input voltages near 1.0 V to assist initial bootstrap charging. This diode is not required for steady-state operation or inputs ≥1.2 V, and its omission reduces BOM cost and PCB area without compromising efficiency above 1.2 V.
How is the output voltage programmed on NCP1410DMR2G?
The output voltage of the NCP1410DMR2G is set externally using a resistor divider from VOUT to GND connected to the FB pin. The formula is VOUT = 1.19 V × (1 + RFB1/RFB2), where RFB2 is typically 200 kΩ and RFB1 is calculated accordingly - e.g., 355 kΩ for 3.3 V output. The internal 1.19 V reference has ±0.6% tolerance at 25°C and <0.03 mV/°C drift, ensuring accurate and stable regulation across temperature and load conditions in the NCP1410DMR2G.
What is the function of the REF pin on NCP1410DMR2G?
The REF pin on the NCP1410DMR2G provides a buffered, high-accuracy 1.19 V ±0.6% reference voltage that serves dual purposes: (1) it acts as the internal feedback reference for output regulation, and (2) it can supply up to 2.5 mA of current to external circuitry - such as ADC references or comparator thresholds - when VOUT ≥ 3.3 V. A 1.0 µF capacitor is required at REF when loaded; 150 nF suffices when unloaded. This eliminates the need for a separate voltage reference IC in space-constrained designs using the NCP1410DMR2G.
Can NCP1410DMR2G be used with lithium-ion batteries?
Yes - the NCP1410DMR2G supports input voltages from 1.0 V to 5.5 V, fully covering the discharge range of a single Li-ion cell (2.7 V to 4.2 V). Its 600 kHz switching frequency, synchronous rectification, and 92% peak efficiency make it ideal for Li-ion-powered portable devices. When configured for 3.3 V or 5.0 V output, the NCP1410DMR2G delivers up to 250 mA while maintaining >85% efficiency across the entire Li-ion voltage range, and its logic-controlled shutdown enables seamless integration with host MCU power management firmware.
