Power/Battery management

DC-DC converters/controllers

  • Integrated switching-mode power supplies (highly-efficient DC-DC converters):
    • Buck, boost, buck/boost, fly-back, … topologies
    • Continuous and discontinuous
    • Voltage and current mode
    • Single phase or multiphase
    • High-frequency – small inductance
    • Asynchronous and synchronous
    • Pulse width modulation (PWM) – Pulse frequency modulation (PFM)
    • Integrated charge pumps and voltage doublers
    • SIMO (Single-Inductor Multiple-Output)
  • Integrated capacitive DC-DCs , charge pumps, voltage doublers

Battery management/charging 

  • Li-ion, PbSO4, ZnO2, …
  • LDO regulators: low quiescent current / high current output
  • Protection circuits: current, voltage and temperature overprotection
  • High-accuracy charging 4.1V ± 10mV (all-in)
  • Wireless charging and battery management: state-of-charge, state-of-health.
  • 24V or 48V automotive supply levels
  • Ultra low leakage <5nA


  • Ultra-fast settling LDOs without external caps
  • Multi-level (3-level) output DC-DC single coil
  • PoE (NCP1083) Integrated 40 W PoE-PD, DC-DC Controller
  • High-speed, low ripple, 2A inductive DC-DC with automatic PFM/PWM switching
  • 60% efficiency, 10V, 20mW integrated Cap-DC-DC
  •  1/2/4-phase 60V, 150W high-frequency (5 MHz), high-bandwidth DC-DC
