Product details
Overview
AP1601M10G-13 from Diodes Incorporated is a PFM-controlled step-up DC/DC converter in MSOP-10L package, designed for 1–4-cell NiMH battery systems. It delivers fixed 3.3V or 5V output with guaranteed start-up below 0.9V input, 90% peak efficiency at 200mA load, and supports up to 1.2A switch current via CLSEL pin selection. Used in pagers, wireless microphones, and portable instruments where ultra-low-voltage start-up and minimal external components are critical.
For engineers reviewing the AP1601M10G-13 datasheet, AP1601M10G-13 pinout, AP1601M10G-13 application, or AP1601M10G-13 equivalent, key selection criteria include its 0.9V start-up capability, dual current-limit configuration (0.4A/0.8A), MSOP-10L thermal resistance (88°C/W), low-quiescent-current PFM control, and compatibility with Schottky diode-based boost topologies.
Technical Context
The AP1601M10G-13 integrates an N-channel/P-channel power MOSFET pair, 1.2V precision reference (±2%), and low-battery comparator with 1.30V threshold on LBI. Its PFM architecture uses constant on-time (3–7 μs) and variable off-time (0.8–1.2 μs) to regulate output voltage across light-to-moderate loads while maintaining high efficiency down to 1mA.
Control logic includes shutdown input (SHDN) with 0.2VOUT/0.8VOUT thresholds, open-drain LBO output with 0.2–0.4V low-state voltage, and CLSEL pin that selects 0.4A or 0.8A internal current limit. The FB pin enables either fixed 3.3V (FB=OUT) or 5V (FB=GND) operation without external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Start-up Voltage | ≤0.9V - enables operation from single NiMH cell at end-of-discharge. |
| Output Voltage Options | 3.3V (FB tied to OUT) or 5.0V (FB grounded) - eliminates external feedback resistors. |
| Switch Current Limit | 0.4A (CLSEL=GND) or 0.8A (CLSEL=OUT) - selectable per load requirement and thermal budget. |
| Efficiency | 90% at VOUT=3.3V, ILOAD=200mA - reduces heat generation in space-constrained portable devices. |
| Quiescent Current | 16–35μA in operation; 0.1–1μA in shutdown - extends battery life during standby. |
| Thermal Resistance | 88°C/W (Junction-to-Ambient, MSOP-10L) - requires minimal PCB copper area for thermal management. |
| Reference Voltage | 1.2V ±2% - sets accuracy of output regulation and low-battery detection threshold. |
Pinout & Package
AP1601M10G-13 is housed in a RoHS-compliant, green MSOP-10L package (3.0mm × 4.9mm × 0.95mm), with exposed thermal pad and 0.5mm pitch. Designed for surface-mount assembly and optimized thermal dissipation via bottom-side copper and vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FB | Feedback Input | Configures output voltage: tied to OUT → 3.3V; grounded → 5.0V. |
| 2 - LBI | Low-Battery Input | Monitors battery voltage; trips at 1.30V to assert LBO when supply drops. |
| 3 - OUT | Power Output | Delivers regulated boost output; supplies bootstrap power to internal circuitry. |
| 4 - LX | Switch Node | Drain connection of integrated N/P-channel MOSFETs; connects to inductor and diode. |
| 5 - GND | Ground Reference | Primary return path for power, control, and reference circuits; ties to thermal pad. |
| 6 - CLSEL | Current-Limit Select | Chooses internal switch current limit: GND → 0.4A; OUT → 0.8A. |
| 7 - REF | 1.2V Reference Output | Stable 1.2V source; bypassed with 0.1μF capacitor for noise immunity. |
| 8 - BATT | Battery Input / Damping Switch | Connects to battery anode; damping switch unused unless specified in design. |
| 9 - SHDN | Shutdown Control | Active-high enable: >0.8×VOUT = ON; <0.2×VOUT = shutdown (0.1μA IQ). |
| 10 - LBO | Low-Battery Open-Drain Output | Asserts low when VLBI < 1.2V; requires 100kΩ pull-up to OUT for system alert. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed sub-0.9V start-up | Enables full functionality from deeply discharged NiMH cells without external assist circuitry. |
| PFM control with ≤100kHz max switching | Reduces switching losses at light loads and allows smaller inductors (e.g., 22μH) and capacitors. |
| Dual current-limit selection (0.4A/0.8A) | Permits optimization of inductor size, efficiency, and thermal performance for specific load profiles. |
| Integrated 1.2V reference with ±2% tolerance | Ensures accurate output regulation and consistent low-battery detection across temperature and process. |
| Open-drain LBO with 0.2–0.4V low-state voltage | Provides reliable battery depletion signal compatible with microcontroller GPIO inputs. |
Applications
| Pagers | Wireless Microphones |
|---|---|
|
Use Scenario: Compact handheld paging units powered by 2–3 NiMH cells requiring stable 3.3V rail for RF IC and display driver. IC Role / Device Role / Timing Role: Primary boost converter supplying regulated 3.3V from decaying battery voltage (1.1–4.2V range). Use Value: Sub-0.9V start-up ensures operation until battery reaches 0.9V/cell, extending usable runtime by ~12% versus comparable converters. |
Use Scenario: Battery-powered UHF wireless microphone transmitter with analog audio front-end and RF power amplifier. IC Role / Device Role / Timing Role: Provides clean 5.0V supply to RF PA stage while rejecting switching noise via PFM's low-noise profile. Use Value: Low output ripple (<15mVpp typical) prevents AM sideband distortion in transmitted audio signal. |
| Electronic Cameras | Pocket Organizers |
|
Use Scenario: Digital still camera using 4-cell NiMH pack to power CCD sensor, flash controller, and LCD backlight driver. IC Role / Device Role / Timing Role: Generates 3.3V for logic and 5.0V for analog subsystems via dual-output configuration (using two AP1601s). Use Value: MSOP-10L footprint (3.0×4.9mm) saves >35% board area versus SO-8 alternatives, enabling thinner camera bodies. |
Use Scenario: Handheld PDA with real-time clock, memory, and touch interface operating from 2-cell NiMH battery. IC Role / Device Role / Timing Role: Supplies 3.3V to microcontroller and peripherals; LBO signal triggers low-power sleep mode before brownout. Use Value: 0.1μA shutdown current minimizes self-discharge loss during weeks-long storage between uses. |
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 |
|---|---|---|---|
| AP6714 | Successor device; higher 1.2A fixed current limit, 92% peak efficiency, integrated soft-start, and AEC-Q200 qualification option. | Supports automotive-grade designs and higher continuous loads (>300mA at 3.3V); requires updated layout for 2.0mm × 2.0mm DFN. | Select AP6714 for new designs requiring extended lifecycle support, higher reliability, or automotive compliance. |
| TPS61099YFFR | TI part; 0.7V start-up, 1.2A switch current, but requires external feedback resistors for 3.3V/5V and lacks LBO output. | Used where ultra-low start-up voltage is mandatory and battery monitoring is handled externally. | Choose TPS61099YFFR only if sub-0.9V start-up is required and LBO functionality is unnecessary. |
Compared with AP6714, AP1601M10G-13 offers simpler fixed-output configuration and legacy footprint compatibility but lacks soft-start and automotive qualification; versus TPS61099YFFR, it provides integrated LBO and resistorless output setting at the cost of slightly higher minimum input voltage.

FAQ
What is the minimum input voltage required to start the AP1601M10G-13?
The AP1601M10G-13 guarantees start-up at ≤0.9V under 1mA load with a Schottky diode (e.g., B0520LW) between input and output. Without the diode, typical start-up occurs at 0.9V and is specified up to 1.1V across temperature. This enables operation from single NiMH cells near end-of-life.
How do I configure the AP1601M10G-13 for 5V output?
Connect the FB pin directly to GND to configure fixed 5.0V output. No external resistors are needed. Ensure CLSEL is set to GND or OUT depending on required current limit (0.4A or 0.8A), and tie SHDN to OUT for normal operation. The REF pin must be bypassed with a 0.1μF ceramic capacitor.
Can the AP1601M10G-13 drive a 300mA load at 3.3V?
Yes - with CLSEL tied to OUT, the AP1601M10G-13 supports up to 420mA steady-state output current at 3.3V (typical). At 300mA, efficiency remains ≥88% with proper layout, 22μH inductor, and low-ESR output capacitor. Thermal derating begins above 85°C ambient due to 88°C/W θJA.
Is the AP1601M10G-13 pin-compatible with the MSOP-8L version (AP1601M8G-13)?
No - the AP1601M10G-13 (MSOP-10L) adds CLSEL and BATT pins not present on the MSOP-8L variant. Pin functions differ: MSOP-8L has LBO and SHDN on pins 7 and 8, while MSOP-10L relocates SHDN to pin 9 and adds CLSEL (pin 6) and BATT (pin 8). Layout redesign is required for migration.
