Product details
Overview
PIP250M from Philips Semiconductors is a fully integrated synchronous buck converter designed as a point-of-load regulator for high-current DC/DC conversion. It integrates two N-channel power MOSFETs, a Schottky diode, and a voltage-mode PWM controller operating at 300 kHz with 0.8 V reference, 15 A output current capability, and built-in overcurrent, overvoltage, and undervoltage protection.
For engineers reviewing the PIP250M datasheet, PIP250M pinout, PIP250M application, or PIP250M equivalent, this device is selected for compact, efficient 5 V input-to-low-voltage (e.g., 1.2–3.3 V) regulation in space-constrained telecom, computing, and embedded systems where minimal external components and thermal performance are critical.
Technical Context
The PIP250M implements voltage-mode PWM control with a fixed 300 kHz oscillator and internal 0.8 V reference. Its integrated power stage eliminates stray inductance by co-packaging upper/lower N-MOSFETs and Schottky diode, enabling fast transient response and reduced EMI.
Protection functions include cycle-by-cycle overcurrent detection via PHASE/OCSET/ENABLE comparison with 30 µs filtering, latch-off after three faults, and independent OVP (1.0 V FB threshold) and UVP (0.5 V FB threshold) with 30 µs delay - all referenced to VSSC and independent of load or input variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 15 A continuous (Tpcb ≤ 110 °C); enables single-chip supply for microprocessors and DSPs |
| Switching Frequency | 300 kHz (250–350 kHz range); balances efficiency, size, and EMI for mid-power POL designs |
| Reference Voltage | 0.8 V (±2.5%); sets regulated output via external resistor divider with tight tolerance on FB pin |
| Input Supply | Single 5 V operation (VDDO = VDDC = 5 V); simplifies system power architecture |
| Protection Features | OCP (latch-off), OVP (1.0 V FB), UVP (0.5 V FB), UVLO (4.1 V start-up); ensures robust fault recovery without external circuitry |
| Thermal Resistance | Rth(j-pcb) = 4–5 K/W; supports high-power density mounting on standard PCB copper areas |
| Efficiency | 88% typical at 2.5 V/15 A output; achieved via synchronous rectification and low-loss integrated MOSFETs |
Pinout & Package
The PIP250M uses the HVQFN68 (SOT687-1) package: 10 × 10 × 0.85 mm thermal-enhanced quad flat no-lead package with 68 terminals and exposed thermal pads (PAD1, PAD2, PAD3) requiring soldering to PCB for electrical and thermal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDO (pins 9,12–17,25,26; PAD2) | Output stage supply | Positive rail for power MOSFETs; must be decoupled near package with low-ESR capacitor |
| VSSO (pins 42–58) | Output stage ground | Power return path for MOSFETs and Schottky diode; connects to PCB ground plane under PAD2 |
| VO (pins 10,18–24,27–41,59; PAD3) | Switched output node | Internal connection to source of upper MOSFET and drain of lower MOSFET; forms main power output |
| VDDC (pins 61,62) | Control circuit supply | +5 V supply for PWM controller and logic; requires RC filter (10 Ω + 1 µF) per datasheet |
| VSSC (pins 8,60,67,68; PAD1) | Control circuit ground | Reference for FB, OCSET/ENABLE, PHASE; must be isolated from VSSO except at single-point PCB tie |
| FB (pin 65) | Voltage feedback input | Inverting input of error amplifier; regulates output by comparing divider voltage to 0.8 V reference |
| OCSET/ENABLE (pins 1,2) | Current limit set & enable | Sets overcurrent threshold via external resistor to VDDO; pulling LOW disables converter |
| PHASE (pin 5) | Current sense input | Connects to VO node; compared against OCSET/ENABLE during high-side conduction for OCP |
| CB (pin 7) | Bootstrap capacitor | Drives gate of upper MOSFET; requires 100 nF ceramic capacitor between CB and VO |
Key Features
| Feature | Design Value |
|---|---|
| Integrated synchronous buck topology | Eliminates external MOSFETs, driver, and Schottky diode - reduces BOM count and layout area by >50% |
| Internal soft-start | 2 ms ramp of reference voltage prevents inrush current into large output capacitors during power-up |
| Remote sensing support | FB pin enables Kelvin connection to load for accurate regulation under PCB trace resistance |
| Thermally enhanced HVQFN68 | Exposed thermal pads (PAD1/PAD2/PAD3) deliver Rth(j-pcb) = 4–5 K/W - critical for 15 A continuous operation |
| Single-supply 5 V operation | Removes need for auxiliary bias supply - simplifies system-level power sequencing and reduces cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54620RGYR | 3.5–17 V input; 20 A max; 450–2000 kHz adjustable frequency; external MOSFETs required | Requires external power stage and more complex loop compensation; better for wide-input industrial use | Choose when input voltage exceeds 5 V or higher frequency/efficiency trade-offs are needed |
| ISL8201MIRZ | 3–14 V input; 10 A max; integrated FETs; 300 kHz fixed frequency; 0.6 V reference | Lower current rating and different reference voltage require redesign of feedback network and output capacitor selection | Consider for space-constrained designs needing similar integration but lower current demand |

FAQ
What is the maximum continuous output current supported by the PIP250M?
The PIP250M delivers up to 15 A average output current when the printed-circuit board temperature (Tpcb) remains at or below 110 °C, as specified in Table 3 of the datasheet. This rating assumes proper thermal design using the HVQFN68 package's exposed pads (PAD1, PAD2, PAD3) soldered to adequate copper area on the PCB.
Does the PIP250M require an external bootstrap capacitor, and what value is recommended?
Yes, the PIP250M requires an external bootstrap capacitor connected between the CB pin and the VO node. A 100 nF ceramic capacitor is recommended per Figure 3 and Section 7.1.4 of the datasheet to ensure reliable gate drive for the upper N-MOSFET under all operating conditions.
How does the overcurrent protection mechanism work in the PIP250M?
The PIP250M detects overcurrent by comparing the PHASE pin voltage (connected to VO) against the OCSET/ENABLE pin voltage during upper-MOSFET conduction. If PHASE falls below OCSET/ENABLE, a 30 µs filtered trip triggers shutdown. Three consecutive trips cause latch-off, requiring VDDC reset below 3.6 V to recover - ensuring robust fault containment without external circuitry.
Can the PIP250M operate from a single 5 V supply, and how is the control circuit powered?
Yes, the PIP250M operates from a single 5 V supply applied to both VDDO and VDDC pins. The control circuit (VDDC) is protected by an external RC filter (10 Ω resistor + 1 µF capacitor) placed close to the pins, as shown in Figure 3. This configuration eliminates the need for auxiliary bias supplies and simplifies system-level power sequencing.
What is the function of the n.c. (no connection) pins on the PIP250M, and how should they be handled?
The PIP250M has seven n.c. pins (3, 4, 6, 11, 63, 64, 66), which have no internal connection. Per Table 2 footnote [2], all n.c. pins must be connected to VSSC (control ground) on the PCB to maintain signal integrity and avoid floating nodes that could induce noise or instability in the feedback or protection circuits.
