General Description
APM3602 is a 2A synchronous buck converter with integrated inductor. The APM3602 with a current-mode control scheme can convert wide input voltage of 2.9V to 5.5V to provide excellent output voltage regulation. The APM3602 is equipped with an automatic Skip/PWM mode operation. At light load, the IC operates in the Skip mode to reduce the switching losses. At heavy load, the IC works in PWM mode. The APM3602 is also equipped with Power-on-reset, soft start, Output Discharge, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package. This device, available in LGA-10 package, provides a very compact system solution to minimize external components and PCB area.

- N-CH MOSFET (105 mΩ) for CH2 High Side
- N-CH MOSFET (60 mΩ) for CH2 Low Side
  • Built in OVP, UVP, Current Limit and OTP
  • Low Cost VTQFN-13 package
  • DyncBandwidthTM Technology

General Description
The APW9202M is a two-channel synchronous mode PWM converter with 3A continuous current capability for one channel and 2A continuous current capability for the other one. Each channel of the APW9202M has independent enable, and it also allows the two regulators to start together by using the same enable signal. Although the switching frequency of the APW9202M is fixed at 800kHz, it can also change the switching frequency via the PWM/SYNC pin. Another feature of this part is its ability to automatically optimize its BW (DyncBandwidth) to allow better dynamic response once it is synchronized to a higher external clock. The APW9202M also provides a 180-degree phase shifting technique to minimize switching noise. The output voltage of each channel can be adjusted using an external resistor divider. Other features include UVP, current limit, and OTP. The APW9202M is available in a VTQFN-13 package with small size and excellent thermal capacity.

General Description
The APW8863D integrates a synchronous buck PWM converter to generate VDD2, a sourcing and sinking LDO linear regulator to generate VDDQ. It offers the lowest total solution cost in system where space is at a premium. The APW8863D provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8863D provides very high efficiency over light to heavy loads with loading-modulated switching frequencies. On TQFN-32 Package, the Forced PWM Mode works nearly at constant frequency for low-noise requirements. The APW8863D is equipped with accurate current-limit, output under-voltage, and output over-voltage protections. A Power-On- Reset function monitors the voltage on VCC prevents wrong operation during power on. The LDO is designed to provide a regulated voltage with bi-directional output current for DDR-SDRAM termination. The device integrates two power transistors to source and sink current up to 1A. It also incorporates current-limit and thermal shutdown protection. The output voltage of VDDQ (LDO) tracks the voltage at VDDQREF. The VDDQ output voltage is only requiring 20µF of ceramic output capacitance for stability and fast transient response. The VDDQEN and EN pins provide the sleep state for VDDQ (S3 state) and suspend state (S4/S5 state) for device, when EN and VDDQEN are both pulled low the device provides the soft-off for VDDQ.
