Product details
Overview
MPC18730EP from Freescale Semiconductor is a power management IC (PMIC) with five regulated outputs-two DC-DC converters and three LDO linear regulators-designed for single-cell Li-Ion (2.7–4.2 V) or Ni-MH/alkaline (0.9–2.2 V) battery-powered portable systems. It delivers programmable output voltages via 3-wire serial interface, supports multiple low-power modes (standby, sleep, wakeup), and integrates PGOOD monitoring and reset control. Used in handheld computing and mobile communication devices requiring compact, multi-rail power sequencing.
For engineers reviewing the MPC18730EP datasheet, MPC18730EP pinout, MPC18730EP application, or MPC18730EP equivalent, key selection criteria include input voltage range compatibility (Li-Ion vs. Ni-MH), independent output voltage programming capability, integrated start-up sequencing control, and Pb-free 64-pin QFN package thermal performance (RθJA = 69°C/W).
Technical Context
The MPC18730EP implements dual configurable DC-DC topologies: in Li-Ion mode, both converters operate as buck regulators (VOUT1: 1.613–3.2 V @ 120 mA; VOUT2: 0.805–1.5 V @ 100 mA); in Ni-MH/dry cell mode, one operates as boost and the other as buck-boost. Each converter features dedicated error amplifiers (EAIN1/EAOUT1, EAIN2/EAOUT2), duty control (DMAX1/DMAX2), and external compensation support.
Three programmable LDOs (SREGO1–SREGO3) accept inputs up to 3.3 V and deliver outputs adjustable via internal DAC and external resistor dividers on SREGC1–SREGC3. The device uses a 176.4 kHz internal oscillator (150–250 kHz range) or optional external clock (EXT_CLOCK), with serial configuration enabling precise startup sequence control via SEQ_SELECT and wake event prioritization across four active-low WAKE inputs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1587AETD+ | Single-output step-down regulator with integrated MOSFET; no LDOs or multi-rail support | Only suitable for fixed 1.5 V or 1.8 V core supply-not a functional replacement for five-rail MPC18730EP | Select only when system requires one regulated rail and minimal footprint; cannot replicate sequencing or battery-flexible operation |
| TPS65120RGTR | Dual-output (positive/negative) charge pump with fixed 3.3 V/–3.3 V; lacks serial programming, LDOs, or battery-type detection | Targeted at LCD bias generation-not applicable for microcontroller multi-rail power domains | Use only for display-specific auxiliary supplies; incompatible with MPC18730EP's system-level PMIC role |
Compared with MAX1587AETD+ and TPS65120RGTR, the MPC18730EP uniquely combines five independently programmable outputs, battery-chemistry-aware DC-DC reconfiguration, and integrated wake/reset sequencing-making it irreplaceable for portable systems requiring flexible, software-controlled power architecture.

FAQ
What battery chemistries does the MPC18730EP support?
The MPC18730EP supports single-cell Li-Ion (2.7–4.2 V), Ni-MH (0.9–2.2 V), and alkaline (0.9–2.2 V) batteries. Configuration is automatic: connect HVB to Li-Ion and leave LVB open; connect LVB to Ni-MH/alkaline and ground HVB. This dual-input architecture eliminates manual hardware changes for multi-chemistry designs, and the MPC18730EP adjusts its DC-DC topology accordingly-buck for Li-Ion, boost/buck-boost for Ni-MH.
How does the MPC18730EP implement programmable output voltages?
The MPC18730EP uses a 3-wire serial interface (DATA/STRB/SCKIN) to write 12-bit configuration words to internal registers controlling DACs for all five outputs. VOUT1 and VOUT2 are set via dedicated registers (Addresses 1 and 4), while SREGO1–SREGO3 voltages are programmed through Addresses 5–7 using external resistor dividers on SREGC1–SREGC3 pins. This allows real-time voltage scaling without soldering changes, and the MPC18730EP retains settings across sleep cycles.
What is the function of the SEQ_SELECT pin on the MPC18730EP?
The SEQ_SELECT pin determines which PGOOD signal (PGOOD1 or PGOOD2) triggers the final wake-up completion event. When SEQ_SELECT is pulled to V_STDBY, the MPC18730EP waits for PGOOD2 assertion before releasing system reset; when grounded, it uses PGOOD1. This enables flexible power sequencing-for example, holding CPU reset until both core (VOUT1) and I/O (VOUT2) rails stabilize-and the MPC18730EP executes this decision autonomously without host processor involvement.
Can the MPC18730EP operate without an external crystal or clock source?
Yes, the MPC18730EP includes an internal oscillator operating at 176.4 kHz (range 150–250 kHz), sufficient for standard DC-DC switching and serial interface timing. The EXT_CLOCK pin is optional: if driven with an external clock (e.g., system master clock), it overrides the internal oscillator for synchronous operation-useful in noise-sensitive environments. The MPC18730EP functions fully with no external clock, simplifying design and reducing BOM cost.
What thermal performance can be expected from the MPC18730EP in a 64-QFN package?
The MPC18730EP in its 64-pin QFN package has a junction-to-ambient thermal resistance (RθJA) of 69°C/W when mounted on a JEDEC-standard 2s2p test board. With proper PCB layout-including thermal vias under the exposed pad and ≥2 cm² copper area-the MPC18730EP sustains continuous 120 mA on VOUT1 and 100 mA on VOUT2 at ambient temperatures up to +65°C. Its Pb-free EP suffix ensures RoHS compliance without compromising thermal conductivity.
